Problem started (I think) only last week, though I can't be sure it isn't connected to a system firmware update on 30 Aug or a Windows update on 31 Aug. I'm running Pegasus 4.72 on Win 10 Professional on a Surface Pro 3, and I don't have time (even if it were possible) to try rolling back the updates.
For months now I've had to make sure I close all folder windows before disconnecting PMail from my university's Exchange server (IMAP connection), otherwise the mailer usually crashes on disconnect.
The last few days, even that hasn't been enough. I close any open folder windows as usual. I then either disconnect the mailbox or leave the IMAP connection on. Then I try to close Pegasus - whether using the X at top right or File | Exit. Quite often, Windows treats the close or Exit command as an unexpected error ("Pegasus Mail for Windows has stopped working") and restarts Pegasus. Sometimes Pegasus seems to close and the first I know is a Windows message that "Pegasus Mail for Windows is restarting". I have to go past the lock screen, reopen the program, and usually it closes OK the second time.
Anyone seeing anything similar or got any ideas? Thanks.
