Well, Ray and Jayson noticed earlier that commenting in IE was broken. After chasing down the wrong path for a decade, it was discovered the some script used to show the Weather.com piece on the site that was breaking it. DOH!

Wonders never cease.

Jayson, thanks for the help debugging, and no, I am still not ready to migrate to CS 2.0 ;) 

Update: I went ahead and changed themes while I was at it. Looks like this one breaks funny in Firefox. I'll probably play with the CSS etc over the weekend.
