Does resizing the window allow the page to render? The boxes next to the x in the top right corner should accomplish this.
Edit: Hmm... there shouldn't be any broken javascript on our forum. You could try uninstalling/reinstalling java as well I suppose.
Edit 2: Another option is to use Firefox or Chrome if you can't get your IE fixed. It's clearly isolated to your browser. Those others work independently of IE and will probably render our site just fine... I am not sure that reinstalling java even impacts regular javascript you see on websites. Anyway, I LOVE Chrome. It's rather snappy, uses little memory, and has a minimalist interface. It's also a very strict browser and renders all sites the way they're intended to be, unlike IE which is the loosest and sometimes goofiest browser I've ever seen.
