Internet Explorer - Extra Space When Not Using Float Element

Hello,

I'm currently coding the website for a team project, which some of you may know, Genesis Extreme. As requested, I'm coding the entire thing in CSS without any tables. So far so good, except for a minor Internet Explorer problem.

Looking in Internet Explorer, it puts extra spaces in two different spots, where I don't use "float:left". I could use float:left, however, the template must be expanded to 100% width of the window. If you define float:left, you must define a width, which I cannot do (obviously).

Here's the link: http://genesisextreme.com/home.php?user=Guest

All of the other browsers that I have tested do not have error and work rather well. If anyone has had this problem before and/or has a suggestion on how to fix this, please let me know. I'm trying to make this as cross-browser compatible as possible.

Thanks.
