You need to give us a little more info.
What browser are you using? (Internet Explorer 6 or 7, Firefox, Opera, etc.)
The white you mention is this the background color on the web pages you visit? Or is it white no matter what backgroundcolor the web page has?
Do you by any chance have a wide screen monitor?
