I had to revise my entire stylesheet to see what the total of all the margins and paddings were set to for left/right sideboxes and center column. I also narrowed it down a lot, thanks for your tip, I'm sure those who still use 800X600 will be thrilled, loll. Everything was trying to squeeze in thus the overlap problem occured.

It seems to be good now, in both FF and IE7...
Take a look if you'd like.
