This page does not render correctly on Internet Explorer 5/6x for Windows. I have detailed the reasons here, but the short form is this: this site relies on standard, validated CSS to render its structure, but Internet Explorer does not support CSS correctly.
If you're using Explorer, first off, I'm sorry about the virus thing, the pop-ups, the crashing, and all that. Seriously consider upgrading to Mozilla. It's free, it's a better browser, and it renders CSS just fine. In the meantime, Sobel, Woody, Barsoom or Stark should work for you.
