I am using Entourage 2008. Have had no problems with it since June when I bought my MacBook Pro. Yesterday it started doing something weird with my mailbox. I have mail structured with an inbox and selected mails going to specific mail folders. It is set up with the reading pane to the right.

As I said no problems till now. The inbox main panel is blank even though the emails are there. Click on the panel and the mail appears but not in the reading pane which stays with an image of the previous mail reviewed. This only happens with my Inbox - the specific mail folders work OK although sometimes the reading Pane is entirely blank. Quitting Entourage fixes the latter but not the former.

I have re-booted several times to no avail.

Does anyone have any clues? Thanks
