[quote user="pgsmick"]One (only one) of the users has lately experienced frequent crashes apparently at random; sometimes creating mail, sometimes downloading, sometimes sending. It reportedly happens 2-3 times a day.[/quote]
Any distinct change before this started? An unexpected connection termination? A new AV scanner? A new printer (driver)? A Pegasus Mail update?
[quote user="pgsmick"]In all cases, Pegasus gives the nondescript "encountered an error and had to close" message.[/quote]
Windows generates this message, not Pegasus Mail.
[quote user="pgsmick"]In November, I saw 17 winpm-32.exe events. 14 were just like the above, one was pointing to the same dll but some other address, one pointed to kernel32.dll, and one was simply an "unknown" dll.[/quote]
The known ones are Windows core modules, it's unlikely (though not impossible) they cause the trouble.
[quote user="pgsmick"]Any suggestions about how to troubleshoot further?[/quote]
A couple of , last resort would be generating a crash dump.
