Site layout issues

Right... so if you are looking at this site in Internet Explorer 6 the right navigation will be all screwed up. I am trying to fix it but not having much luck. I fixed most of it for Internet Explorer 7 and Firefox but there are still little quirks. If you are using Safari on a Mac things will look just as they should. For security reasons you should be using Internet Explorer 7 or Firefox if your on a Windows machine anyway.
