I have the same problem... explorer.exe crashes and restarts when I open certain folders. So far its been folders containing mp3 files, album art and ini files - it doesn't crash when I open files containing just mp3 files though...?
I have XP with SP2. The details of the error message say a different file caused the restart almost every time - sometimes ntdll.dll, sometimes msvcrt.dll, sometimes shell32.dll, ole32.dll ....
Was a solution found to this problem?
