I am experiencing problems with Entourage 2004. It worked fine until about 3 weeks ago. Now it freezes in Mail. The beach ball appears when I view a message - especially if I try to delete it - and I have to Force Quit. I have tried removing the Preview Pane - but it does not help. I cannot find reference to this problem on the Entourage support site. I am using the latest updated Panther on an iMac G5. Suggestions?
