I have a problem with my XP install - my explorer.exe keeps on restarting - everything else is Ok and it has no ill effects other than a couple of seconds wait whilst it restarts - but i want to get to the cause of the problem. Trouble is - i can't find any error messages, i once had a window coming up saying :- Microsoft Visuall C++ Runtime error. C:\Windows\explorer.exe The application needs to be restarted. I have checked Event Viewer and it shows:- The shell stopped unexpectedly and Explorer.exe was restarted. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. There are no bytes or other information that might be of use. Any idea how i can track down this error - happens about once an hour.
