Very strange. After posting, I went back to the front page, tried it again and it's not working. Went back into this topic and tried it and it's working. It's like every other time I go to a page on this site it works, and the other times it doesn't. Weird.
Edit: Hmmm, if I go to a page, whether it's the front page or a topic, if it's not working, when I hit F5 to refresh the page, it works. Strange.
