I'm not sure if this is happening for anyone else, but recently, every time I visit the front page of the site (not forum), after a few seconds I get a message saying "Warning: Unresponsive script" and I have the option to "stop script" or "continue". If anything, my guess is that the side ad bar is a little screwy, being that that's the only thing that doesn't load when I choose "stop script".
FYI, I'm using Firefox 2.0.0.12 (latest version I think)
