Something is failing to write/delete on exit.  First try to manually delete the deleted messages folder.  If that does not help take a good look at the hierarch.pm file.

Pegasus 4.41 is now crashing intermittently on exit.  It didn't do this when first installed so perhaps some Windoze update caused it.  I haven't been able to notice any consistency in the current message display.

Anyway, I keep dismissing the debugger options (asking if I want to debug the program) after a crash.  Does anyone want this data?  I could bring the crashed task into the vs2005 debugger and dump anything that was needed - or set up one of the other crashdumpers for a mini or full dump.
