Try giving your wife's user account administrator privileges
temporarily and see if everything works fine then. If so, you haven't
yet checked permissions on the relevant file(s).
PowerMail can write to surprising things. In 4.1 (haven't tried 5.x
yet), PowerMail writes at quit time to AppleScript files in the PowerMail
Scripts folder (inside the application package) that were run from the
Scripts menu during the session (can't imagine why it does this). If the
user doesn't have write access (non-admin OS X users don't after a
standard install), the program crashes (bad error handling!). Took me
quite a while to associate the script-running activity with the crashes.
Sounds like something similar might be going on here.
