We run 3 identical MC 3.1.3 systems tied to Unity. For months one of the systems crashes out of MC immeadiatly when the Import or Export command is used. Never even gets to the point of selecting what to import or what type of file to export - crashes as soon as Import or Export is selected - no error message, MC just vanishes back to the XP desktop.
With 2 other systems available for file I/O we've just worked around it. All 3 systems are identical in hardware and software versions. We've reinstalled MC few times on the problem system and it operates normally in all other respects. I've been working on Avids for the better part of 15 years and can usually track down problems but this one...!
My guess is something in XP is shutting it down but I don't know what. I've checked the XP Event Viewer for odd happenings but see nothing out of the ordinary.
