Windows 7: Pegasus Mail process sporadically fails to terminate

Pegasus Mail process sporadically fails to terminate

I have looked through this forum at several other threads regarding processes failing to terminate but none of them seem to match my problem so here goes.

Since switching from XP to W7 last Christmas my email client Pegasus Mail (pmail) sporadically fails to terminate correctly - the gui closes but the underlying process is still active and causes any further opening of the client to fail. The only solution found so far is a Task Manager kill and very often that leaves the Pegasus lock file lying around (but not always).

Interestingly, this seems to be the only process suffering from this problem on my home PC but I have experienced similar problems at work (we also switched to W7 at Christmas) with different (bespoke) processes. This failure has been demonstrated on both 32 and 64 bit machines at work.

The guys at Pegasus Mail couldn't come up with any answers and apparently haven't seen this problem before. A lot of experimentation at work seemed to suggest that changing the Windows "mode", e.g. back to Classic, made matters worse but this wasn't conclusive and the problem persisted with the native W7.

For information, Pegasus Mail is a text-based email client which essentially consists of a directory with a fairly large number of files, at least one per email message. My suspicion is that the application hasn't managed to release all it's resources, e.g. file handles, and therefore can't close. So I guess I have 2 questions - (1) has anyone else come across this problem with Pegasus Mail (and solved it), and (2) can anyone tell me how I might pin this down further, e.g. with Windows debug type tools?
