IE Floating lists problem

[J0nny]

Hi guys, I have yet-another-IE-problem. I've used browsershots.org to take a look at my site in 18 browsers, and the ONLY browser in which it looks bad is IE 4-7.
Here's what it looks like in IE7.

What the heck is up with the diagonal list?!
Here's what it SHOULD look like (FF2).

It's a <ul> inside of an <li> which is clear:both;. If you need any of the code, just say, or take a look on my local server, I'll try to leave it online.

I can't open your page, so I can't check the code.

Make sure all your ul and li tags are opened and closed in the correct order.
