Hi Jérôme, thanks for the suggestion. However, it was something else. The 'unexpectedly quit' symptome even prevailed when the PowerMail User Folder was empty. So it had to be something user-specific, but on system level. I used a tool to delete all local system caches and, surprise surprise, new windows open again in PowerMail, without crashing the application. No idea how and which cache got currupted.
So, all is well again and my wife is back to heavy powermailing ;-) Cheers, Karsten Liere > >Try to delete the "Custom Dictionary" file from your PowerMail user >folder.
