Hi, my first post here so please be gentle!

I have a very annoying problem with Outlook 2007.

I start up Outlook and get a list of unread messages
I click on first message in inbox and it is displayed
After reading the message I click delete
The first message deletes and the header for next message in the list comes on the screen, just the header, no message content.
At this point Outlook hangs. I have two windowns open: the new message and Inbox but nothing responds.
The only way out is to do CTRL ALT DELETE and quit all Outlook tasks with Task Manager.
If I then restart Outlook it then usually works just fine.

Any ideas?

I have not (yet) reinstalled Outlook - as I dont want to lose all my messages and settings.

Thanks
