I'll give it a shot. It's doing it in Firefox, IE and Opera. Otherwise it's working just great.

It's also intermittent. I had a bunch of users point it out, and it was happening to me as well. However this morning (albeit on a much faster connection) I can't duplicate it.
Where's the call to that image actually located? I had to make a folder just for it, and I'd much rather have it in /forum/images where it belongs.
Thanks again!
