I don't think you are looking in the right place -- or you have some MASSIVE cache settings.
At the very top of the page, you don't see a private message from me that came in at: 1/9/2004 8:11:22 PM?
I did a database query and you have 94 messages in your mailbox. I know they are in your box properly because of the way the database shows them as unread. And nobody else has any problems with their box showing up.
