The page is so riddled with errors its rather hard to know what is going on. You might find that after you have fixed all the errors things behave more predictably.

Validate your site and fix all the errors listed. When you get through you will probably find it easier to troubleshoot any strange rendering issues. (This might fix your IE issues as well)

If you fix the problems and still need help just post here again.

You might also want to consider getting rid of all the tables used for layout. Tables should not be used for layout purposes (unless you are hopelessly trapped in the 1990s). Use CSS for positioning.

Edit: and one more thing. Moving to XHTML 1.1 Strict might fix some of your IE issues you mentioned in your other thread.
 
Hey, thanks for your help, I appreciate it. I'll get rid of the table I was using. :p

I figured out that it was the infamous clearfix bug. Happy, happy, it's behaving now. The IE fix was my bad....I had bad math in the CSS Div callouts. Firefox was just polite in letting it slide, while IE was more strict about it.

I validated my CSS, but the HTML is how it came, and other sites using it have the same HTML problems as I. So what I'm saying is while I can screw around with CSS, I'm wary of messing with the HTML, especially now that I got it running.
 
Looks like most of the validation errors are the result of this being html not xhtml. It looks like there might be an unclosed tag there somewhere though. but for the most part nothing terribly serious. I'd still suggest you fix it though. Bad code slows down browsers even if they are able to understand it.
