[Resolved] IE bug. Can help anyone fix?

I get a bug in IE where the sidebar pushes the content div down. My site is http://nverted.org. I checked and it works fine in firefox, opera, and safari. I havent checked IE6 though. But in IE7 the content is pushed down. Can anyone help?

I know the cause of the problem is because I am using two divs to wrap the whole page, but they are aligned properly and work fine in all other browsers.
