You must be playing on MySpace. We have no control over their advertisements and the placement of them. I suggest that you contact MySpace directly and let them know that this ad is interfering with your game play.
i keep hearing about this t moble? i have yet to have the problem, try pop up blocker, or increase your internet security.....
use kaspersky internet security combined with the settings in your browser to block pop ups and you wont see a pop up ever again!
