Page displays black diamonds with question marks across the top
When I go to a certain account site and log-in, my account page displays as a blank page with black diamonds with question marks spread across the to of the page.
This situation sometimes occurs in some other non-user account sites with embedded advertisements. In the advertisement box, the word "Advertisement" shows at the top worth a spread of black diamonds with question marks.
I tried clearing all cookies and preferences with no change. I also set the site to allow cookies from the site. In Internet Explorer this problem does not occur.
