and technically web designing you should be designing for specifications that are the norm (i believe it's the 1020x760 or whatever it is... i forget)
The google ads aren't showing up anymore, they were disabled, you sure? There are ads there, but not the google ads. Lemme know if this is still an issue with the scrollbar at the bottom of the screen.
And yes, I know, the site was corrected for that resolution awhile back, I'm just relaying what I have my monitor set on and stating I'm not experiencing the issue.
So if I know:
1. Is it still happening?
2. What is your monitor resolution?
3. Does it happen on every page or only specific pages or only with specific ads, etc?
