Similar subject to luci2a post a little while back.
At the office I can see the most charming things on this site, such as Grinler running with scissors inspite of his admonition not to, and Bear's quill pen, and JE's kitty cat. In any case nothing there, nothing moves. Smilies do move.
I allow mobile code, 4 kinds of scripts, ads, for this site. So why can't I see the fun stuff?
I, too, have Zone Alarm Suite but haven't really learned how to use it yet.

In IE go to Tools, Internet Options. Then click on the advanced tab. Scroll down to multimedia, and make sure there is a checkmark in Play animations

Grinler, you run with scissors!
The strange thing is that after I read your post, I did just what you suggested - but the play animations was already checked. And you weren't running.
Now, having read the other post, about smilies, here I was going to report how it didn't work, yet it does. Baffling.

It is strange... In the past i had similar problems where the animated gif would sometimes work and sometimes not. Then i would refresh the page and it would work. Ever since i upgraded to the latest firefox everything has been good for me
