I don't really post at the other forums anymore except the HD, but saw some people talking about GIFs not moving anymore. I've found the latest version of Google Chrome seems to do this. Not sure if this helps or not, but I thought I'd mention it. Firefox is still working like a champ, though.
I love Google Chrome, and find it way faster and more light on resources than the other browsers, but there are some quirks that keep be from using it full-time.
