You mean that guy ^? MEANIE HEAD! :) Sorry I've been off TSC for a while and I'm just acting a little immature whilst getting track of the new updates.
And 1 suggestion: You can't see which message icon is selected until after you post.
You're using IE6. I'm guessing it's an IE bug. In Firefox, Konqueror, and probably other standards-compliant browsers (Opera, Safari, etc), the selected icon appears with a white border.
I might try writing an IE-specific hack later, but you're better off upgrading to a better browser. <_<
