Fixed Background Causes Adsense To Shake (Reward for Fix)

When I use a fixed background on my site, adsense (and any javascript ads) "shake" when using FireFox 2. The ads display fine in Internet Explorer 7 and FireFox 3 though.

You can see what I mean here: http://www.gtaiv.cc

When I change the background to scroll the ads display fine in FireFox 2.

How can I fix it so that the ads don't "shake" in FireFox 2 while having a fixed background?

Whoever gives me a working resolution, I will reward $5.00 via paypal. It's not much, but it's all I can afford right now.

Thanks

 

I can't be bothered to find your CSS from the 1 billion CSS files linked inside your CSS, the only thing that could be doing such a thing is due to the way you have "styled the ad"
So basically you have something unessecary added to the CSS for the DIV that the Ad is inside. As far as i'm concerned the only thing you'd need to add is margin: 0px auto; to center the ad, and nothing else.

 

That is a side-effect of transparancy with the javascripted adverts being in an iframe. iFrames are separate 'windows' from the page content, and as such only render in their new position AFTER the page it is contained on itself renders.

I'm not aware of any real workaround apart from not using transparancies, which render like crap slowing most computers to a crawl in the first place when used over such a large area.

That and the total train wreck the page ends up in IE6...
