It's a Java issue. I beliueve it is Adsafeprotected that has the old (outdated) code. But could be others, too. You can fix it temporarily by setting Shockwave Java to Always activate, but I know a lot of people are not going to want to do this. I think there would be an even better solution and that is if a script in some kind of window like that stops working it automatically kills it and just puts a blank page.
