Problems with CSS

I imported the default pages from the XWiki homepage, everything looks fine except for the frontpage. It seems like a CSS problem. I've tried to view the page in Firefox 2.0 and IE6. In IE6 the panel menu ( which is supposed to be located right) appears in the top-left corner. In Firefox it appears bottom-left. Sometimes it displays correctly, but not as often as it displays incorrect. When I click another link the menu displays where it should ( top-right) You can take a look at it here: http://mypal.kicks-ass.org:8180/xwiki/bin/view/Main/WebHome -- if(!Coffee.Exists) { me.Dispose(); throw new NullCoffeeException(); }
