Website Bug list

While we've been working on this web site for several months, new bugs are occasionally popping up. I'm starting this thread as a central place to collect problems. When you post here, please remember to tell us what browser and platform (mac osx6, windows 7, etc.) you're using, especially if you've verified the issue on more than one browser. We know there are some minor incompatibilities with older versions of Internet Explorer (IE6, IE7)--mostly stuff with the menus.
