Yes -

My Windows Live Mail account is only displaying new messages from my contacts.  If I get a new message from someone other than someone in my contacts, it shows up in my Inbox for about 2 seconds, and then disappears.  It's not in my junk box, or deleted folder.  And in fact, it still shows that I have "one new message" in the lower right corner of the screen.  But I can't find or see the message.  And I've even looked in the "all unread e-mail" folder, and still nothing.   

So what appears to be happening is this: I'm getting e-mails as normal.  However, if they are not from someone in my contact lists, they are not displaying.

Thanks.
