Here's a puzzling problem - maybe somebody has an idea. Right now I am out of ideas.
On Win7 64bit, the following crashes Notepad:
On Desktop, right click, select "New | Text Document". This creates "New Text Document.txt".
Right click on that file, select "Edit". This opens notepad with the empty file.
Select "File | Save as": Notepad crashes and Win7 reports that "Notepad has stopped working".
Now, move the file to c:\temp and repeat steps 2 and 3: no crash this time and the save-as dialog appears normally. I can create similar steps for the "open" dialog.
Things I have tried:
Safe mode - does not work, same problem
Create a new user and try again logged in as that user - no crash
Name file differently, or create elsewhere and then move to desktop - same problem
Use Wordpad instead - same problem
Review shell extensions with ShellExView - nothing extraordinary here
Stare at the event log entries for each of the crashes. Does not enlighten me.
At time of crash look at the process explorer stack view. Hangs at a function "TaskDialog".
sfc.exe /scannow repaired some files but the problem persists.
This is how the event log entries look like:

What else should I try, short of dumping my user and starting over with a new profile? Thanks...
