For the past several days Outlook 2000 SP4 on Win 2000 Pro SP4 has been
behaving very strange.

When I delete an open email, it seems to have been deleted, but the open
email stays on the screen until I click the mouse anyplace on the screen -
then the screen updates and the previously deleted email closes.

I've scanned for viruses and don't have any.

Anybody ever experience this? And if so, how can I fix it?

Regards,
Alan
