  • Memory leak in Google Chrome

    - by jasondavis
    As a developer it is very common for me to have 2-3 different IDE's open, 10-15 google chrome windows which can hold up to 200 open tabs (I know I get out of hand some times), Photoshop, couple twitter bots for promo, and a few other programs but my system still runs fast and smooth. I have an i7 processor with 12gb ram. Now with all my usual stuff running my Physical memory is usually running around 50-60% however over the course of the day or much less even, I will gradually grow to 98% The highest Memory usage processes will be from Google Chrome, if I sort in the task manager by highest memory usage and end the 1 highest process which will be a google chrome one, my memory usage will jump back down to about 60%. Also by ending that 1 process, all my Chrome windows will remain open and in use, so it doesn't affect me at all by ending that process. Based on this research I am assuming that that 1 runaway process is likely the Adobe Flash as I also can say that it gets up to the 98% much faster when I am using flash items like video or music player. But even without using any of them it will still climb up to that high number eventually. Has anyone else experienced similar results?

  • Can you "swap" the Sysprep answer file in Windows 7

    - by Ben
    I have a load of new Lenovo laptops which I am due to distribute in my company. We are distributed in multiple locations and I want to ship the laptops "boxed" and untouched by IT hand for distribution. We are using LANDesk to do all the software distribution and provisioning, but are currently falling at the first hurdle as when booted, the laptops kick into the Lenovo mini-setup wizard. I assume this is because they have been sysprepped at Lenovo. In order to keep with our (almost) zero touch strategy I want the users to PXE boot into a PE of some sort, which will run a script on startup which replaces the sysprep answer file with one of my own. (i.e. prepopulated with product key, company info etc.) and then reboot to complete Sysprep. The plan is that this will run, and then install the LANDesk agent as a post-sysprep task, which in turn will complete the provisioning. Anyone have any experience / know any pitfalls to look out for / can suggest a suitable, PXE-bootable PE environment? Apologies for the verbosity of the question - it takes a bit of explaining! Thanks in advance, Ben

  • NRPE unable to read output, but why?

    - by ticktockhouse
    I have this problem with NRPE, all the stuff I've found so far on the net seems to point me at things I've already tried. # /usr/local/nagios/plugins/check_nrpe -H nrpeclient gives NRPE v2.12 as expected. Running the command by hand (as defined in nrpe.cfg on "nrpeclient", gives the expected response nrpe.cfg: command[check_openmanage]=/usr/lib/nagios/plugins/additional/check_openmanage -s -e -b ctrl_driver=0 bat_charge "Expected response" But if I try to run the command from the Nagios server I get the following: # /usr/local/nagios/plugins/check_nrpe -H comxps -c check_openmanage NRPE: Unable to read output Can anyone think of anywhere else I might have made a mistake with this? I've done the same thing on multiple other servers with no problem. The only difference I can think of with this is that this box is RHEL 5 based, whereas the others are RHEL 4 based. Those two bits above that I've tested are the what most people seem to suggest when people have had this problem. I should mention that I get a weird error in the logs when I restart nrpe: nrpe[14534]: Unable to open config file '/usr/local/nagios/etc/nrpe.cfg' for reading nrpe[14534]: Continuing with errors... nrpe[14535]: Starting up daemon nrpe[14535]: Warning: Daemon is configured to accept command arguments from clients! nrpe[14535]: Listening for connections on port 5666 nrpe[14535]: Allowing connections from: bodbck,combck,nam-bck Even though, it's plainly reading that /usr/local/nagios/etc/nrpe.cfg file to get the stuff it's talking about further down..

  • MS SQL Server slows down over time?

    - by Dave Holland
    Have any of you experienced the following, and have you found a solution: A large part of our website's back-end is MS SQL Server 2005. Every week or two weeks the site begins running slower - and I see queries taking longer and longer to complete in SQL. I have a query that I like to use: USE master select text,wait_time,blocking_session_id AS "Block", percent_complete, * from sys.dm_exec_requests CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 order by start_time asc Which is fairly useful... it gives a snapshot of everything that's running right at that moment against your SQL server. What's nice is that even if your CPU is pegged at 100% for some reason and Activity Monitor is refusing to load (I'm sure some of you have been there) this query still returns and you can see what query is killing your DB. When I run this, or Activity Monitor during the times that SQL has begun to slow down I don't see any specific queries causing the issue - they are ALL running slower across the board. If I restart the MS SQL Service then everything is fine, it speeds right up - for a week or two until it happens again. Nothing that I can think of has changed, but this just started a few months ago... Ideas? --Added Please note that when this database slowdown happens it doesn't matter if we are getting 100K page views an hour (busier time of day) or 10K page views an hour (slow time) the queries all take a longer time to complete than normal. The server isn't really under stress - the CPU isn't high, the disk usage doesn't seem to be out of control... it feels like index fragmentation or something of the sort but that doesn't seem to be the case. As far as pasting results of the query I pasted above I really can't do that. The Query above lists the login of the user performing the task, the entire query, etc etc.. and I'd really not like to hand out the names of my databases, tables, columns and the logins online :)... I can tell you that the queries running at that time are normal, standard queries for our site that run all the time, nothing out of the norm.

  • Can't connect to a Hyper-V VM from anywhere but the host OS

    - by Elbelcho
    I have an unusual situation on hand where I'm able to connect to a Hyper-V guest VM from the HOST, but not from anywhere but the host. The VM is running WIn2k8R2 and has IIS installed and Remote Desktop enabled. If I browse to the IP from the host OS, the IIS7 page displays. I can also RDP into the guest OS from the host as well as ping. From OFF the host, RDP, web and ping all fail. If I completely shut off the guest VM's firewall, ping will then start to respond, but all RDP and port 80 still don't. The physical host machine has 2 nics installed, but only one is plugged in. The one plugged in has a static IP. I have one Hyper-V virtual network and it's set to external. The guest VM has one NIC with a different static IP than the host, but both are on the same subnet. The host machine is joined to the domain, the guest VM is not. Any sugestions? Thanks so much for any help you may be able to provide!

  • charging light on in laptop with battery removed.

    - by Jus12
    I hope this is the right place for this question. I have an LG R310 laptop. Recently the adapter connector started playing up, so I got a second hand replacement adapter of the same rating. The adapter was a cheap type (I know I made a mistake) and faulty.. it made a low buzzing sound when plugged in and not connected to the laptop. It didn't make the noise when connected to the laptop. Foolishly I used this adapter for several weeks. One day the adapter stopped working. The led didnt work and it was not charging. It had also drained the laptop's battery to 0%. I then got an original replacement adapter. Now I can use the laptop on power but the battery does not charge. The charging light does not come on. The interesting thing is that when I remove the battery the charging light comes on and stays on after I insert the battery back (the battery still does not charge). I need to know if the faulty adapter damaged the motherboard or if its just a problem with the battery. I have a multimeter and I prefer not to open the laptop. Thanks in advance.

  • Using pre-made patch cables on a punch down block?

    - by Trevor Harrison
    I need to add a 24 port switch to my wiring closet. In the (distant) past, I usually just punched each port of the switch to a 110 block on the wall (using hand-made cables), and cross connect between that and the 110 block that has the runs to each workstation. To save time, I'm thinking of buying 12 pre-made drop cables, cutting them in half (so 24 single ended cables), and punching those to my 110 block. The things I'm worried about are wire type (ie. solid vs. strands) and color scheme. I really don't know if they use different wire types (still?), but I remember that being an issue at one point. Can anyone comment on this? (I definitely won't feel comfortable trying to punch stranded wiring on my 110 block) Also, picking up a random pre-built cable I had laying around, I noticed that the color scheme used didn't appear to be T568B, but T568A, which would clash with the rest of my wall. Anyone know of an online source that specifies these things? I've looked at www.cablesforless.com (which does have nicer prices) and www.cablestogo.com (which seem stupid expensive) so far. Cables For Less doesn't specify wiring scheme, Cables To Go does specify T568B. Both seem to specify stranded wires instead of solid.

  • Windows 7 autostarting apps as administrator

    - by Fujishiro
    Hello everyone. The question is easy to answer I guess. (Tried to search here, didn't find an answer.) So. The deal: There is a bug in OpenOffice (haha ..just one? :)), which prevents the spellcheck. You have to start it with right-click , run as administrator to make it work. Tried also setting this at the 'properties', but it didn't work. But 'quickstart.exe' would be also enough to make this work. (OpenOffice's quickstarter). So I'd like to run it at boot, as an admin, like I'd do with right-click. How to do THAT? (Actually there is a different bug for spellcheck on Win7. One have to run oowriter.exe as an admin, and then install the extension BY HAND from Program Files...\share...*.oxt. And THEN it'll work IF you run the app as an admin. (I'll buy SoftMaker's office as soon as the hu spellcheck arrives, but until then I have to make this work. Thanks for the answers in advance.))

  • Good PC-based video conference control tools?

    - by Jeremy Wadhams
    I'm looking to improve the user experience in our video conference rooms, by simplifying the things users do all the time (setting up a call, muting and unmuting, panning and zooming between a few room-appropriate presets) and totally taking away the functions that we don't use or that are more likely to ruin the experience (changing the brightness of the TV, using the VNC presenter mode). The rooms each have Tandberg Edge or MXP video units, I'm not looking at PC-based solutions like Skype or iChat. The classic way to do this would be to plunk down huge money for an AMX or Crestron panel. This does have some advantages, and I am considering that approach, but in my initial investigation, that looks expensive, inflexible, and proprietary. On the other hand, the Tandberg video units I'm looking to control are very thorough XML API (PDF), so some of the integration magic that Crestron and AMX consider to be a value add, I could reproduce at mashup speeds. Anyone aware of an Open Source or Commercial product that takes advantage of the readily available web APIs, some simple touch screen PCs, and builds a product that is more like skinning an AJAX web app, and ideally more cost effective than the proprietary panels?

  • Outlook and IMAP - Outlook doesn't allow the Drafts and Trash folders to sync with the respective IMAP folders

    - by Matt
    I'm using Outlook 2007 and Outlook 2010 against an IMAP server (the problem exists across many, like Gmail, you name it). Outlook lets you set your Outlook "Sent" folder to map to the IMAP server's Sent folder (the other choice is to map your Outlook Sent to your Personal Folders Sent) - this is good. When you send a message from Outlook and then look in the sent folder of the IMAP server (e.g. from a different client or from a browser), the messages are there. This is the behavior I want. Outlook does NOT support the same behavior for Drafts and Trash. In both cases, items deleted (or Drafts saved) in Outlook go in to Outlook's local folders and do NOT show on the IMAP server's Trash or Drafts folders. Same problem in reverse. Thunderbird on the other hand does support the proper mapping of Drafts, Sent and Trash. I expected this to be IMAP-specific but it appears to be client specific. What does Outlook implement it this way and is there a workaround?

  • Windows CE restores default configuration after restart (Motorola MC3190)

    - by jarek
    Good morning, everyone! I have a problem with Motorola MC3190 hand scanner running on Windows CE. I've got few of those to make a new program for some kind of warehouse. There is already installed program which have been used by the customers before, so I delete this one and instead I install my new software which I've just made. It is running very well, but when I take out the battery and leave the device for entire night without power supply, it restores the whole configuration, so the old program is back, the wireless configuration is back and... Yeah. The scanner is restored to the configuration which was running when I received it few weeks ago. What I want to do is to set the whole configuration of the scanner so after a long power-off my program and my configuration will be restored. I truly believe someone knows how to do it. The time is running out, and I believe that the customer will be kind of annoyed when he will change the battery and the program which he bought will be gone. ;-) Regards, Jarek

  • How to direct reverse proxy requests using wildcard vhosts

    - by HonoredMule
    I'm interested in running a reverse proxy with 2-3 virtual machines behind it. Each internal server will run multiple virtual hosts, and rather than manually configuring each individual vhost on the proxy (a variety of vhosts come and go too often for this to be practical), I would like to use something which can employ pattern matching in a sequential order to find the appropriate back-end server. For example: Server 1: *.dev.mysite.com Server 2: *.stage.mysite.com Server 3: *.mysite.com, dev.mysite.com, stage.mysite.com, mysite.com Server 4: * In the above configuration, task.dev.mysite.com would go to Server 1, dev.mysite.com would go to Server 3, yoursite.stage.mysite.com to Server 2, www.mysite.com to Server 3, and yoursite.com to Server 4. I've looked into using Squid, Varnish, and nginx so far. I have my opinions regarding their respective desirability and general suitability, but it's not readily apparent if any of them can handle dynamic server selection in this manner and not require per-vhost configuration. Apache on the other hand can do this handily and simply, but otherwise (aside from being well-known and familiar) seems very poorly suited to the partly-performance-serving task. Performance isn't actually a major concern yet, but it seems foolish to use Apache if another system will perform far better and can also handle the desired 'hands-free' configuration. But so is frequently having to adjust the gateway for all production services and risk network-wide outage...and so also is setting oneself up for longer downtime later if Apache becomes a too-small bottleneck. Which of these (or other) reverse proxies can do it/would do it best? And maybe I should post this as a separate question, but if Apache is the only practical option, how safe/reliable/predictable is apache-mpm-event in apache2.2 (Ubuntu 12.04.1) particularly for a dedicated reverse proxy? As I understand it the Event MPM was declared "safe" as of 2.4 but it's unclear whether reaching stability in 2.4 has any implications for the older (2.2) versions available in official/stable package channels of various distros.

  • Mac Management Without Permission and Security

    - by Bart Silverstrim
    I was going through some literature on managing OS X laptops and asked someone some questions about usage scenarios when using the MacBooks. I asked someone more knowledgeable than I about whether it was possible for my Mac to be taken over if I were visiting another site for a conference or if I went on a wifi network at a local coffee house with policies from an OS X Server with workgroup manager (either legit for the site or someone running a version of OS X Server on hardware they have hidden somewhere on the network), which apparently could be set up to do things like limit my access to Finder or impose other neat whiz-bang management features. He said that it is indeed possible for it to happen as it would be assigned via the DHCP server and the OS X server would assume my Mac is a guest and could hand out restrictions and apparently my Mac will happily accept them without notifying me or giving me an option, unlike Windows which I believe would need to be joined to a domain before it becomes "managed" by Active Directory. So my question is as network admins and sysadmins with users traveling with MacBooks, is there a way to reasonably protect your users from having their machines hijacked without resorting to just turning off networking all the time? Or isn't this much of a security hazard? What threat does this pose to the road warriors in your businesses?

  • Most transparent way to connect two LANS using a WET610N Wireless Bridge

    - by Spencer Ruport
    I have two wired systems hooked to a Linksys WRT54GL wired/wireless router which is also hooked to my internet. I'll refer to this as LAN1. I have two more systems in another room that are connected wirelessly. Recently I decided I would much rather have another wired LAN in the other room and use a bridge to connect them. This would be LAN2. Prior to hooking up the device I assumed that the ethernet side of the bridge would have a DHCP server so that I could simply hook it up to a switch and I'd be on my way. However that isn't the case which leads me to believe I'll have to add one to LAN2 correct? Or is there some way to have the DHCP from LAN1 also hand out IP addresses to LAN2? If I do need a DHCP device on LAN2 what would be best? Another hardware device or should I just install some DHCP software on one of the systems (since they're both on 24/7 anyway). Any recommendations would be appreciated. :)

  • New keyboard for linux: Adesso Tru-Form or MS Natural Keyboard 4000?

    - by Andrea
    Hi folks! I'm going to buy a new ergonomic keyboard for my laptop. In the following, keep in mind I live in Italy. I considered the following models: Adesso PCK-308UB - Adesso Tru-Form™ Pro - Contoured Ergonomic Keyboard with TouchPad-PS2 Pro: has a built-in touchpad in the same position of my laptop somewhat cheaper than the alternative below Cons: the surface doesn't seem to be bowl-shaped. keys seem to lay on a straight slightly-inclined surface. It seems an idea used extensively in other ergonomic keyboards according to a few comments on the net, new Adesso keyboards seem to lack robustness, they're likely to loose small parts after a few weeks or months. Other users, instead, seem to never had any problem in years and swear by their quality and comfortability. Those who had problems, however, lamented a lack of responsiveness from the manufacturer. I'm not sure whether the keyboard, at least the standard keys, and the touchpad will both be recognized correctly under linux distros (I mostly use FC btw) last time I checked, Adesso didn't have local resellers in my country Microsoft Natural Ergonomic Keyboard Pro: recognized as one of the most comfortable keyboards reliable customer service operating in my country AFAIK there are several documented ways to get extra buttons work with linux Cons: it doesn't have a builtin touchpad and has a numeric keypad wasting space to reach mouse But there could be other keyboards I haven't considered yet, so here follows my ideal keyboard wishlist, ordered by priority linux compatible basic ergonomic design, which entails split tilted keyboard and pads advanced ergonomic design, like true-ergonomic's or kinesis , where special keys (like enter, caps-lock...) are placed symmetrically in the middle to be used by thumbs a builtin touchpad/trackball placed under the keyboard. I just love this on my notebook. I think it's pretty effective, since it allows my hand to rest naturally everytime I use it. Any opinion on this? high-quality switches, like cherry's (unsure about this one) additional programmable keys placed near usual ones, to simplify typing shortcuts TIA Andrea

  • Migrating Windows 2003 File Server Cluster to Windows 2008 R2 Standalone?

    - by Tatas
    We have a situation where we have an aging Windows 2003 File Server Cluster that we'd like to move to a standalone Windows Server 2008 R2 VM that resides in our Hyper-V R2 installation. We see no need to keep the Clustering as Hyper-V is now providing our Failover/Redundancy. Usually, in a standalone file server migration we migrate the data, preserving NTFS permissions and then export the sharing permissions from the registry and import them on the new server. This does not appear possible in this instance, as the 2003 cluster stores the sharing permissions quite differently. My question is, how would one perform this type of migration? Is it even possible? My current lead is the File Server Migration Toolkit, however I can find no information on the net about migrating from cluster to standalone, only the opposite. Please help. UPDATE: We ended up getting the data copied over (permissions intact), but had to recreate the shares manually by hand. It was a bit of a pain but it did in the end work out.

  • Syncronization between folders MAC OS Lion

    - by Andre Carvalho
    I have an iMac at home and I use a Macbook pro for work. I also have a time capsule at home containing my main folder with my main files. I use it as a NAS besides the Time Machine backup tool. I have several personal files I need to be accessing both at home and at work. My wife, who works at home, uses sometimes the same .XLS files and .DOC files I might have used during my day at work, away from home. My question is: Is there a software, or tool that a I can use to sync my iMac and my MB Pro folders? Remembering that: There might be a chance that my wife and I have changed the same files during the day, so the files would have to be merged so none of the information added by either me or my wife would be lost. The software/tool that would be installed on the MB Pro would need to mount the Time Capsule volume so it could locate the main folder on it. It has to be done automatically when my MB is at home ( with a schedule option ); I have tested some softwares like synctwofolders and Chronosync but none fulfilled all my needs. The first couldn't mount the Time Capsule Volume and didn't have the many schedule options. I really liked Chronosync, but it doesn't merge the files. When it detects a conflict ( for instance: my wife changed a .DOC file on the iMAC and I changed the same file on the MB it asks you to choose which version you want to keep instead of allowing you simply to merge them ). I don't have much experience with automator or scripts but maybe you can give me a hand with that.

  • Why Is Web Sharing Broken on My Mac?

    - by Sam Murray-Sutton
    Background: I use my Mac for web development, running copies of web sites locally. I recently installed the Snow Leopard update, which to all intents and purposes seems to have gone fine, except... What's not working? Web-sharing; more specifically I can't turn it on via preferences. The preference pane just hangs when I try to. So Apache doesn't start on reboot. I can start Apache by hand, but I don't know enough to either setup apache to start with the computer, or to properly fix web sharing. Further details My Apache error log shows nothing on when the system boots up (as I would expect). This is the error message when I try to start web sharing from the sharing preference pane. 28/09/2009 10:58:05 System Preferences[834] setInetDServiceEnabled failed with 1 for org.apache.httpd Here's the messages given when I start apache from the command line.

Any help would be greatly appreciated. UPDATE I have added an answer of my own below - I was able to solve it thanks to being pointed in the right direction by the comments below, so thanks very much. But I'm still not totally clear as to what caused the problem or how my solution addressed it, so I'm leaving the question open for now.

  • Best CPUs for speeding up compiling times of C++ w/ DistGCC

    - by Jay
    I'm putting together a distributed build farm with DistGCC to speed up our teams compile times and just looking for thoughts on which processors to use in the hosts. Are we going to get a noticeable decrease in time using 8 cores vs. 4-hyperthreaded cores? Big difference in time between i7 and Xeon? etc, etc. Just need advice from people who've put together kick-a build clusters. We've got a majority of the normal things to speed up builds in place (pre-compiled headers, ccache, local gigabit connections between them, tons of ram, etc) so please just give advice on the best processor to use. And money is a factor, but anythings doable if the performance increase is noticeable. Thanks. Jay EDIT: Although any advice IS welcome, please refrain from "Do this first" posts as we're not planning on skimping on things like SSD, maxed out RAM, etc. My personal system is a iMac Quad-core i5 with 8GB of RAM. When I build our project locally, my processor floats around 99-100% a majority of the time, which makes me assume it is a bottleneck, even if you made everything else faster. My ram on the other hand doesn't even get close to maxing out. It's also worth noting that I did research this, however every discussion I could find was primarily for gaming machines, which is obviously a different beast in usage. These machines won't even have monitors or anything but integrated graphics since they have one purpose: Build freakin fast. (hopefully)

Jay EDIT: Although any advice IS welcome, please refrain from "Do this first" posts as we're not planning on skimping on things like SSD, maxed out RAM, etc. My personal system is a iMac Quad-core i5 with 8GB of RAM. When I build our project locally, my processor floats around 99-100% a majority of the time, which makes me assume it is a bottleneck, even if you made everything else faster. My ram on the other hand doesn't even get close to maxing out. It's also worth noting that I did research this, however every discussion I could find was primarily for gaming machines, which is obviously a different beast in usage. These machines won't even have monitors or anything but integrated graphics since they have one purpose: Build freakin fast. (hopefully)

  • Providing access to a Samba server for VPN clients

    - by Kamil Kisiel
    We have some Windows users that connect to our network via VPN from home. They need to be able to connect to our Samba server and access a mapped network drive just as they do as when they are on our LAN. The complication is that VPN clients are placed on a subnet other than our office LAN, and behind a firewall. What's the easiest way for me to allow them to still connect to the network share? The solutions I've currently seen involve setting up a WINS server for name resolution purposes and then tunnelling a bunch of the NetBIOS stuff through the firewall. However that means I'd have to set up the VPN DHCP server to hand out the WINS address, something I'm not even sure is possible on the Cisco hardware we have. I'm thinking there must be an easier way. Should I use an LMHOSTS file? Or just map by IP address? Also, I'm not terribly familiar with Windows networking, so which ports would I need to pass through my firewall in order to get the file sharing through?

  • What LTO 4 drive to buy

    - by pplrppl
    Evan Anderson mentioned in another solution you could buy a LTO-4 (autoloader, 1 tape / day) - $4,566.00 (the discussion included total cost of tapes for a specific rotation.) but I don't know specifics on what he or you would recommend for the actual drive and if necessary controller. Show me a newegg URL or CDW, Dell, or HP, or whatever your favorite vendor would be for your solution if you don't mind looking it up or just give me a brand and a model number and I'll be glad to do the leg work myself. I currently have on have on hand an external LTO 3 drive that uses LVD SCSI interface (and thus have a controller card that has an external LVD SCSI connector). If that card isn't sufficient to interface to a LTO 4 drive let me know. http://www.fujifilmusa.com/shared/bin/LTO_Overview.pdf shows minimum tape speeds for LTO4 and other LTO formats. It looks like the IBM LTO4 actually has a lower minimum speed than the IBM LTO3. Either way my average server is too slow to feed LTO3/4 without shoeshining so I'm looking for a drive with a low minimum write speed. If you trust the PDF from 2008 that makes my choices IBM LTO 4 full height IBM LTO 4 half height HP LTO 4 half height but presumably there are other options out there that weren't mentioned in the fuji PDF. Again I'm looking for a specific recommendation on a drive to buy (and the controller if needed).

  • How can I set Vim to obey accents of my spoken language?

    - by naxa
    When pressing w or e in sentences with accents (written in my native language), such as the first one (marked **) here: **Éj-mélybol fölzengo** - csing-ling-ling - száncsengo. Száncsengo - csing-ling-ling - tél csendjén halkan ring. [1] the characters o, ö, among others [2], make my gVim think they are word-ends so it stops on them (in Normal mode). gVim stops on the positions marked with _ where it shouldn't: Éj-mélyb_ol f_ölzeng_o. I would like to set gVim so it properly handle words even when containing accents and other local characters. But where do I set this? I use it on Win32, vim v 7.3.46. [1] - excerpt of a poem by Weöres Sándor [2] - "others", not mentioned here :) like í, u are also a problem. On the other hand, gVim seems to already work with é and á. gVim version info: VIM - Vi IMproved 7.3 (2010 Aug 15, compiled Oct 27 2010 17:59:02) Included patches: 1-46 Compiled by Bram@KIBAALE Big version with GUI.
