Sorry, this doesn't work in any current Internet Explorer. Maybe version 9 will work when it comes out.
Hate to do this to you, but I only have so many hours in the day.
I feel bad for you if you're a corporate user stuck with Internet Explorer...you might see if you can get away with Chrome Frame.
A "degraded" experience means you pretty well can't do anything on this page. Really, you don't want to see the attempt. It's pretty ugly.
