Problem with Outlook 2007

I have this problem with outlook 2007. When I get a email and open it. It doesn't show it as being read. If I right click on it and select Mark as read. It still doesn't! I am having to close and reopen outlook and then select "Mark as read" and it will..

Any ideas?

When I get home. I'll try a reinstall and see if that fixes it.

None of the links posted were able to fix this.

Thanks for your help.
