Right sidebar disappears in IE6

I can't figure out why my right sidebar just disappears in IE6. Has anyone ever encountered this issue? Here's the site I'm building:

If you go to NetRenderer.com at http://ipinfo.info/netrenderer/index.php, you'll see that there is no right nav. However, it shows up beautifully in IE 7 on firefox and on IE. Any thoughts?
