• Bad results converting PDF to EPS on Linux

  - by Tim

  I'm having some trouble converting PDFs (created by Adobe Illustrator on a Mac) to EPS. I have tried several things but I am wondering if there is a better option. The following list is ordered by decreasing quality: inkscape --export-area-page --export-eps=out.eps in.pdf using the graphical program Inkscape works best, but is a bit slow; pdftops -eps in.pdf out.eps uses Poppler and works good and is fast; pdf2ps in.pdf out.eps uses ghostscript and works ok for simple documents; convert in.pdf out.eps uses ImageMagick and always rasterizes the image. I haven't tested the following: acroread -toPostScript use acroread (Linux only) Some issues I've found: Transparency is not supported in EPS, but instead of flattening the layers, most programs rasterize the image producing big files and ugly graphs. Inkscape does this best by only rasterizing the unsupported area. Gradients are rendered properly by Inkscape, but Poppler somehow chops up the gradient into many shapes of different colors. Greek symbols are seemingly not supported by Ghostscript and are rasterized (using pdf2ps). What are your experiences for this kind of task? Did I forgot certain programs and/or command line options that improve quality? I found some posts on this, but not a (thorough) comparison of possibilities, please correct me if I'm wrong.

• Windows, never "lose focus" of the current window

  - by Mazura

  I want the task bar to light up orange and never lose focus to anything. If I'm installing something and then go play a game at some point it will drop out to the finished instillation. Also, if installing multiple programs at once my 'next' button can all of sudden become "click here to install this crappy toolbar" of another program's install. Of course there are settings for some programs to not "lose focus" or "stay on top" but I really want windows to handle it. If its somehow an exe called say, Taskswtich.exe, I could possibly use Process Blocker however I'm assuming its part of a function call or some such. For XP I found this: How to disable auto focus of opened Windows applications? but what about Windows7? And this old post Preventing applications from stealing focus with a bunch of long answers that say "no". I'd appreciate this not being merged with a 4 year old question. I'd like to avoid 3rd party software. This is 2014, don't we know how to hack windows yet?

• Win7 - Some pinned program's icons are corrupt, show default

  - by Andrew Backer

  I have both FF 3.6 & Chrome pinned to my taskbar in win7. The icons for these two programs show up as the ugly default icon from yesteryear. Strange. Is there some way to force an icon refresh for pinned programs? When I first added them they showed properly, but several days later they reverted to this state Un-pinning the program causes the icon to show up properly, and re-pinning it causes it to break again. These other proggies show up fine: Media Center, Media Player Classic HC, Hulu Desktop, WMP, and the folders. I have 2 user accounts on this box, and both are showing this behavior. I have tried changing the taskbar icon size to 'small' and back, but to no effect. Edit (Add) The icons show up as broken in the start menu too, but I can navigate to the EXE directly. When I click "change icon" in the properties for the start menu entry I get the error : Can not find %ProgramFiles%\Google\Chrome...\chrome.exe.

• Windows 7 - Windwos XP - sharing - why isn't working?

  - by durumdara

  Hi! This is seems to be "hardware" and not "software" / "programming" question, but I need to use this share in my programs, so it is "close to programming". We had an XP based wireless network. The server is XP Professional, the clients are XP Home (Notebooks). This was working well with folder sharing (with user rights, not simple share). Then we replaced the one of the notebook with Win7/X64 notebook. First time this can reach the server, and the another client too. Later I went to another sites, and connect to another servers, another networks. And then, when I return to this network, I saw that I cannot connect to this server. Nothing of resources I see, and when try to dbl click on this computer, I got login window, where I can write anything, never I can login... The interesting part, that: Another XP home can see the server, can login as quest, or with other user. The server can see the XP home notebook. The Win7 can see the notebook's shared folders, and XP home can see the Win7 shared folders. The server can see the Win7 folders, BUT: the Win7 cannot see the server folders. Cannot see the resources too... The Win7 is in "work networking group", the group name is not mshome. I tried everything on the server, I tried to remove MS client, restore it with simple sharing, set guest password, etc., but I lost the possibilities to access this server from Win7. Does anyone have any idea what I need to see, what I need to set to access these resource - to use them in my programs? Thanks for every info, link: dd

• Investigating a potential CPU failure

  - by Jernej

  On a Ubuntu server that I am using for computations I have recently observed that some CPU extensive programs (GUROBI,CPLEX) often segfault. Being in correspondence with tech support of the respective programs I was suggested that it may be a hardware issue. The administrator of the server performed a detailed memtest and it turned out that the RAM modules appear to be fine. Hence I've used the tool mprime to test the CPU and the following two lines appear multiple times durring the execution of the stress tests: [Worker #4 Oct 18 18:47] FATAL ERROR: Rounding was 0.498046875, expected less than 0.4 [Worker #4 Oct 18 18:47] Hardware failure detected, consult stress.txt file. The stress.txt file in itself is not very verbose about what could be the cause of this error so I would like to ask whether anyone here happens to know what could be the cause of this issue? Is there some other test I could perform to nail the problem even further? The temperature of the system (and all cores) was fine during the entire stress test (+69.0°C (high = +80.0°C, crit = +98.0°C)) the CPU in question is a Intel Core i7-2600K CPU @ 3.40GHz and is not overclocked or modified in any way. Also what is interesting that if I run mprime to only stress the CPU all tests pass fine. The error is only triggered when I let mprime stress the CPU+RAM.

• Why can't I open file with doubleklick after I moved the application that opens it on windows?

  - by Glen S. Dalton

  I am on windows server 2003, but I guess it is the same on windows xp. I moved some movable applications (usually people create them for usb sticks) to locations like c:\bin\app1\app1.exe. The old location was c:\programs\app1\app1.exe app1.exe can open files of type *.ap1 When I rightclick file.ap1 and choose open with ... the Open with dialog appears. But it is not working how I expect in this situation. I can choose c:\bin\app1\app1.exe with the "Browse" button, but: app1.exe will not appear in the dialog where I just choosed it in the programs list, like I am used to it after clicking OK on it in the browse dialog. app1.exe will not open it when I click ok in the "Open with" dialog, the application that was assigned until then will still open it What could be the reason? my account is member of the administrators group I just changed the permissions of the folder c:\bin\app1\ and made sure that the group "Administrators" has all rights. I also inherited this manually to all subfodlers and subfiles. I also tried to move the application (with the whole folder) to "c:\program files\app1\app1.exe

• Blue screen error code 1000008e

  - by Kas

  I'm getting blue screens, mostly when trying to boot a program that required a lot of memory (games, photo editing software.) So far I've only managed to catch one set of error codes: BCCode: 1000008e BCP1: C0000005 BCP2: ADA393BA BCP3: E9BCEBC4 BCP4: 00000000 OS Version: 6_0_6002 Service Pack: 2_0 Product: 768_1 It's on a Sony VAIO Laptop VGN FW-41E, Vista OS service pack 2. Besides these codes it lists two 'temporary' files that were related with this crash: ...AppData\Local\Temp\WER-134925-0.sysdata.xml ...AppData\Local\Temp\WERDA66.tmp.version.txt When I googled these files some site said it was linked to a worm called 'yodo', but virus scans don't return any results (hitman pro, malware bytes, avast antivirus all turn up empty). Upon further searching about this yodo worm, I came across security stronghold where someone posted they had acquired this worm when downloading access and excel templates. Now, I actually did download templates for the same programs, they might have been the same, they may be related or I might be grasping at straws here. I have not noticed any issues other in performance as of late, just BSOD's when I start software that requires some memory, but I never had issues with these exact same programs before. Help and/or hints are required on how to actually figure out what's the root of this BSOD issue and how can I fix it. Do you reckon it's actually a virus? What program should be able to remove YODO worm stuff?

• Program for remove exact duplicate files while caching search results

  - by John Thomas

  We need a Windows 7 program to remove/check the duplicates but our situation is somewhat different than the standard one for which there are enough programs. We have a fairly large static archive (collection) of photos spread on several disks. Let's call them Disk A..M. We have also some disks (let's call them Disk 1..9) which contain some duplicates which are to be found on disks A..M. We want to add to our collection new disks (N, O, P... aso.) which will contain the photos from disks 1..9 but, of course, we don't want to have any photos two (or more) times. Of course, theoretically, the task can be solved with a regular file duplicate remover but the time needed will be very big. Ideally, AFAIS now, the real solution would be a program which will scan the disks A..M, store the file sizes/hashes of the photos in an indexed database/file(s) and will check the new disks (1..9) against this database. However I have hard time to find such a program (if exists). Other things to note: we consider that the Disks A..M (the collection) doesn't have any duplicates on them the file names might be changed we aren't interested in approximated (fuzzy) comparison which can be found in some photo comparing programs. We hunt for exact duplicate files. we aren't afraid of command line. :-) we need to work on Win7/XP we prefer (of course) to be freeware TIA for any suggestions, John Th.

• Keyboard's media keys are blocked by a program

  - by Mike Hanson

  I've got a Microsoft Natural Ergonomic Keyboard 4000. In addition to the regular keys, it's also got keys for Web/Home, Search, Mail, Favorites (5), Calculator, and Media functions (Mute, Volume Up/Down, and Play/Pause). Everything works most of the time, and the exception is rather odd. I use a programming system called Clarion. When that has focus, the Media keys don't work. (All the others still do.) I've also discovered that programs that I create using Clarion also block the media keys (only when they have focus). This indicates that it's probably something in Clarion's Run-Time Library (RTL) that's causing the trouble. The keys will work if I click on a non-Clarion window before hitting the media key, but that's an undesirable hassle. The odd thing is that I have many colleagues with the same keyboard, and they have no problem. When I recently upgraded from Vista Professional to Win7 Ultimate, I noticed that various things "appear" differently. For example, with my old system, when I changed the volume or muted the volume bar visualization always appeared at the bottom right on the screen. Now it doesn't appear in certain programs, even when it works. This indicates an order of precedence for visual elements. I'm fairly certain a similar order of precedence exists for keyboard hooks. Depending on how the hooks are defined, and the order in which they're applied, it would seem that sometimes the IntelliType drivers don't see the media keystrokes. The Media keys probably behave differently than the rest of the "special" keys, because they are more of a standard across all keyboards, so perhaps are handled by a different driver hooking mechanism. Does anyone have any suggestions of how I might fix this problem? Is there some way to change the order of hooks? Delay the loading of the IntelliType driver? Thanks in advance!

• Windows, why 8 GB of RAM feel like a few MB?

  - by Desmond Hume

  I'm on Windows 7 x64 with 4-core Intel i7 and 8 GB of RAM, but lately it feels like my computer's "RAM" is located solely on the hard drive. Here is what the task manager shows: The total amount of memory used by the processes in the list is just about 1 GB. And what is happening on my computer for a few days now is that one program (Cataloger.exe) is continually processing large quantities of (rather big) files, repeatedly opening and reading them for the purposes of cataloging. But it doesn't grow too much in memory and stays about that size, about 90 MB. However, the amount of data it processes in, say, 30 minutes can be measured in gigabytes. So my guess was that Windows file caching has something to do with it. And after some research on the topic, I came across this program, called RamMap, that displays detailed info on a computer's RAM. Here is the screenshot: So to me it looks like Windows keeps in RAM huge amounts of data that is no longer needed, redirecting any RAM allocation requests to the pagefile on the hard drive. Even when I close Cataloger.exe, the RamMap reports the size of the mapped file as about the same for a long time on. And it's not just this particular program. Earlier I noticed that similar slowdown occurred after some massive file operations with other programs. So it's really not an exception. Whatever it is, it slows down the computer by like 50 times. Opening a new tab in Chrome takes 20-30 seconds, opening a new program can take up to a minute. Due to the slowdown, some programs even crash. So what do you think, is the problem hiding in file caching or somewhere else? How do I solve it?

• What is the difference between disabling hibernation and idling time for a NAS?

  - by Gary M. Mugford

  I have two D-LINK DNS-323 NAS boxes with two Seagate drives in each. The first one is about a year old, the second one about three months. The first two on Monster are each 1.5T drives while the last two on Origami are 2T drives. I have never been overly happy with the Monster drives but, outside of poor throughput on small files, they have been consistently available to all programs after I put a batch file into my startup to do a directly listing of each. I added the two new drives when I added the Origami box. But, watching the dos box that comes up, I rarely see both listed before the box disappears. Other programs, backups, Belarc, even my file browsers, seem to have a dickens of a time seeing O: and P:. Finally, I decided to go into setup and turn off hibernation. Performance HAS been better since and Belarc, for instance, now sees both drives. At the time of poking around, I noticed an Idle Time feature too. What is the difference between the two settings? And for added points, how much trouble am I in for turning off hibernation? The super bonus round ... anything ELSE I should have done? Thanks in advance, GM

• Backing up default windows installation with dd from linux running on another partition - is this fe

  - by Marek

  I am preparing to reinstall my system. I am thinking about creating a multi boot with a linux distro+Windows 7 to choose from when starting up. I would love to be able to skip all the hassle of reinstalling Windows and all programs when it starts becoming too slow in the future, thus I would like to mirror my fresh Windows system partition with some programs preinstalled. I am thinking about installing Ubuntu, making a partition for windows, installing windows with the basic environment (Visual Studio, Office, etc.) then booting into Linux and making an image of the windows partition with dd. I am not familiar with linux at all so I am a little afraid something may go wrong along the way. Is it possible to do it this way? Will I be able to partition my existing disk for multi boot easily after I install Ubuntu? Will I be able to recover the Windows partition easily using dd when I will need to re-create a fresh windows partition in the future? What other (better) approach can you recommend to achieve the goal of easy disk mirroring (for free)?

• How to burn a data DVD in Windows XP

  - by SabreWolfy

  I am trying to burn a data DVD (DVD+R) in Windows XP SP3 on a Dell desktop computer. The computer has a licensed copy of Nero 6.3. Nero indicates that an update to version 6.6 is available, but after following the link provided, it redirects me to the Nero website to purchase the upgrade. I'm not interested in doing this. After creating a project in Nero 6.3, inserting a blank DVD+R and trying to start burning the data DVD, Nero indicates that I should insert an appropriate disk into the drive. It does not seem to detect the blank DVD+R. I downloaded infrarecorder and cdrtfe from Sourceforge. Neither of these programs worked either. They both indicated that I should insert the correct media, with cdrtfe saying there is no disk in the drive. I tried with another blank DVD +R with the same effect. I inserted a CDR containing data into the drive and the Windows read read this CDR without a problem. I have no reason to believe that the drive is faulty. I am aware that Windows XP itself is not able to burn DVDs. However, it seems that three third-party software programs are not able to burn a data DVD in Window XP. The specifications provided in Nero indicate that DVD+R is compatible with the drive. How can I burn a backup data DVD in Windows XP?

• How to troubleshoot when one has no idea where to start?

  - by Chris Walton

  I am looking for hints, tips and answers on how to get started on troubleshooting when: The problem is intermittent The problem could lie literally anywhere - operating system; free source software; my own software developments; purchased software; crumbs on the keyboard; the specific combination of software I am currently running; Maxwell's demon; the little blue men actually running the machine have gone on strike; etc. I have expertise only in a few of the areas that are potential candidates for the cause of the problem. The specific problem I am having is detailed below as an example, but I am not seeking answers to my current problem, but rather where and how to start on tackling such problems. I am currently encountering a problem with my new machine. On a few occasions the machine has just frozen; not accepting keystrokes, mouseclicks, or anything except the power on/off switch. Invariably I have been merely browsing the web; I have had a few (<= 6 other applications) running. None of these applications are major; and represent a mix of commercial programs and open source programs, typically migrated from Unix of some variety. My machine is a Windows 7 I7 quad core laptop.

• How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

  - by sauparna

  I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

• Running $ORIGIN linked binaries from setuid scripts on linux

  - by drscroogemcduck

  I'm using suidperl to run some programs that require root permissions. however, the runtime linker won't expand library paths which contain $ORIGIN entries so the programs i want to run (jstack from java) won't run. more info here There is one exception to the advice to make heavy use of $ORIGIN. The runtime linker will not expand tokens like $ORIGIN for secure (setuid) applications. This should not be a problem in the vast majority of cases. my program looks something like this: #!/usr/bin/perl $ENV{PATH} = "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.6.0_12/bin:/root/bin"; $ENV{JAVA_HOME} = "/usr/java/jdk1.6.0_12"; open(FILE, '/var/run/kil.pid'); $pid = <FILE>; close(FILE); chomp($pid); if ($pid =~ /^(\d+)/) { $pid = $1; } else { die 'nopid'; } system( "/usr/java/jdk1.6.0_12/bin/jstack", "$pid"); is there any way to fork off a child process in a way so that the linker will work correctly.

• Search behavior of Windows 7 start menu

  - by Kevin Ivarsen

  I'm coming to Windows 7 from XP, and there are aspects of the start menu search that I like. However, there are some behaviors that seem either inconsistent or surprising to me. For example: If I type "Pa" into the search bar, Paint is the first result (under the "Programs" heading), and it is selected for me. I can just hit Enter to start the program If I have a standalone exe "testing" on my desktop, and I type "test", the program comes up as the first item (under the "Files" heading), but it is not selected for me. I have to hit down-down-down-enter to open it from the keyboard. The same appears to be true for shortcuts and folders. What classifies something as a "Program" verses a "File"? Is there any way to configure the start menu so that the first search result is always selected? As a heavy keyboard user, it seems insane for the behavior to be inconsistent, and to require so many keypresses to select the top result. Also, are there resources that document the details, limitations, and tricks of the start menu search? (For example, a "Proc Exp" search will match "Process Explorer", but not "ProcessExplorer") EDIT: I've found that instead of hitting down-down-down to select the first item (when no Programs are in the list), you can just hit tab. This helps a bit, but the inconsistent behavior still makes this search feature more awkward and frustrating than necessary.

• How can I switch from a custom linux network namespace back to the default one?

  - by Martin

  With ip netns exec you can execute a command in a custom network namespace - but is there also a way to execute a command in the default namespace? For example, after executing these two commands: sudo ip netns add test_ns sudo ip netns exec test_ns bash How can the newly created bash execute programs in the default network namespace? There is no ip netns exec default or anything similar as far as I've found. My scenario is: I want to run a SSH server in a separate network namespace (to keep the rest of the system unaware of the network connection, as the system is used for network testing), but want to be able to execute programs in the default network namespace via the SSH connection. What I've found out so far: Created network namespaces are listed as files under /var/run/netns (but there is no file for the default namespace) The ip netns exec code can be found here: http://git.kernel.org/cgit/linux/kernel/git/shemminger/iproute2.git/tree/ip/ipnetns.c#n132 - I haven't grasped everything that it is doing yet, but it doesn't look very promising. ip netns identify $$ as suggested by Howto query and change network namespace on linux? returns nothing when in the default network namespace

• UDP blocked by Windows XP Firewall when sending to local machine

  - by user36367

  I work for a software development company but the issue doesn't seem to be programming-related. Here is my setup: Windows XP Professional with Service Pack 3, all updated Program that sends UDP datagrams Program that receives UDP datagrams Windows Firewall set to allow inbound UDP datagrams on a specific port (Scope: Subnet) If I send a UDP datagram on any port to other, similar machines, it goes through. If I send the UDP datagram to the same computer running the program that sends (whether using broadcast, localhost IP or the specific IP of the machine), the receiver program gets nothing. I've traced the problem down to the Windows XP Firewall, as Windows 7 does not have this problem (and I do not wish to sully my hands with Vista). If the exception I create for that UDP port in the WinXP firewall is set for a Scope of Subnet the datagram is blocked, but if I set it to All Computers or specifically enter my network settings (192.168.2.161 or 192.168.2.0/255.255.255.0) it works fine. Using different UDP ports makes no difference. I've tried different programs to reproduce this problem (ServerTalk to send and either IP Port Spy or PortPeeker to receive) to make sure it's not our code that's the issue, and those programs' datagrams were blocked as well. Also, that computer only has one network interface, so there are no additional network weirdness. I receive my IP from a DHCP server, so this is a straightforward setup. Given that it doesn't happen in Windows 7 I must assume it's a defect in the Windows XP Firewall, but I'd think someone else would have encountered this problem before. Has anyone encountered anything like this? Any ideas?

• Reduce "Metafile" memory usage?

  - by Jay Conrod

  My work computer (Windows 7 64-bit) spends a lot of time swapping memory when I switch between programs. This surprises me since I have 4 GB of RAM, and the programs I use aren't particularly RAM hungry (Outlook, Emacs, p4win, Firefox, various build tools). I downloaded RAMMap, and it shows over a gigabyte of memory used by "Metafile". From the Sysinternals blog: Metafile is part of the system cache and consists of NTFS metadata. NTFS metadata includes the MFT as well as the other various NTFS metadata files. ... In the MFT each file attribute record takes 1k and each file has at least one attribute record. Add to this the other NTFS metadata files and you can see why the Metafile category can grow quite large on servers with lots of files. So I understand what the "Metafile" data is... I work on large builds comprising hundreds of thousands of files (none are that big, but they add up to several gigabytes). My question is how can I reduce the amount of memory used by "Metafile"? I'm not actively using all those files at once, so why does Windows need to keep info in RAM? Restarting my machine every time I sync a new build is really annoying.

This should not be a problem in the vast majority of cases. my program looks something like this: #!/usr/bin/perl $ENV{PATH} = "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.6.0_12/bin:/root/bin"; $ENV{JAVA_HOME} = "/usr/java/jdk1.6.0_12"; open(FILE, '/var/run/kil.pid'); $pid = <FILE>; close(FILE); chomp($pid); if ($pid =~ /^(\d+)/) { $pid = $1; } else { die 'nopid'; } system( "/usr/java/jdk1.6.0_12/bin/jstack", "$pid"); is there any way to fork off a child process in a way so that the linker will work correctly.

• Problems installing Windows service via Group Policy in a domain

  - by CraneStyle

  I'm reasonably new to Group Policy administration and I'm trying to deploy an MSI installer via Active Directory to install a service. In reality, I'm a software developer trying to test how my service will be installed in a domain environment. My test environment: Server 2003 Domain Controller About 10 machines (between XP SP3, and server 2008) all joined to my domain. No real other setup, or active directory configuration has been done apart from things like getting DNS right. I suspect that I may be missing a step in Group Policy that says I need to grant an explicit permission somewhere, but I have no idea where that might be or what it will say. What I've done: I followed the documentation from Microsoft in How to Deploy Software via Group Policy, so I believe all those steps are correct (I used the UNC path, verified NTFS permissions, I have verified the computers and users are members of groups that are assigned to receive the policy etc). If I deploy the software via the Computer Configuration, when I reboot the target machine I get the following: When the computer starts up it logs Event ID 108, and says "Failed to apply changes to software installation settings. Software changes could not be applied. A previous log entry with details should exist. The error was: An operations error occurred." There are no previous log entries to check, which is weird because if it ever actually tried to invoke the windows installer it should log any sort of failure of my application's installer. If I open a command prompt and manually run: msiexec /qb /i \\[host]\[share]\installer.msi It installs the service just fine. If I deploy the software via the User Configuration, when I log that user in the Event Log says that software changes were applied successfully, but my service isn't installed. However, when deployed via the User configuration even though it's not installed when I go to Control Panel - Add/Remove Programs and click on Add New Programs my service installer is being advertised and I can install/remove it from there. (this does not happen when it's assigned to computers) Hopefully that wall of text was enough information to get me going, thanks all for the help.

• Completed downloads freeze Windows

  - by Ben Hooper

  The Issue Shortly after a file download via Google Chrome for Windows completes, the download will get stuck on "0 seconds left" and all other programs (except Google Chrome, for some reason, but browsing will not work) completely freezes into Windows' infamous "Not Responding" state, affecting Explorer particularly badly. Eventually, the programs will recover themselves but they will recover significantly faster if you cancel the file download, relative to how quickly you react. Performing the exact same operation immediately after cancelling the download usually works without issue. This issue occurs when with any file type (.ZIP, .MSI, .MSG, .PNG, .URL, etc) of any size from any source (Dropbox, SourceForge, Imgur, even tiny and locally-generated BLObs created by my own Chrome extension, etc) to any location.   Potential Causes As this issue is so inconsistent, I haven't been able to prove whether the issue is Chrome-specific or being caused by my system or my Chrome configuration but it's happening on both my work and home PCs. I originally suspected that this issue was being caused by security software scanning completed downloads for threats but I'm not as confident in that theory anymore as the issue persisted even after changing my security software from ESET NOD32 and Malwarebytes Anti-Malware Pro to ESET Endpoint to Microsoft Security Essentials.   System Information (of both PCs) Windows version: 7 Service Pack 1 64-bit Google Chrome version: 30.0.1599.101 (but has been happening for a long time)   Screenshots
