At first I thought it was just in any other browsers besides IE because Microsoft is a dick and does not test in other browsers, but that’s not the case. Running this website on IE, with SilverLight turned off, gives the same result.
Bing is getting a TON of press lately, and I am sure millions of people are hitting this website. What does it say about your product when you can’t even get a simple CSS rule right?
Other minor annoyances:
1) The hover state for the button flickers because it’s not aligned correctly
3) What is the hell is up with capitalizing file names? URI are case sensitive, just try changing Default.html to default.html and you get a “Page Not Found”.
Come on Microsoft, it’s not that hard.
