What version of windows and what browser are you using?
I checked this out and have a solution for each browser.
For IE: Use Firefox
For Firefox: Get Adblock
Adblock prevents ads from showing up on a website. Someone else had entered your EXACT problem for Firefox but no one had responded to him on the forum so I could offer you no help. However, Adblock is an extension that can be found at www.texturizer.net
and it MAY help your problem.
