Hi,
I noticed yesterday that the emoticon panel on homepage (for those who want to put a smiley in the shoutbox) is always on background, the screenshots at the bottom of the page are displayed above it.
Maybe the <DIV></DIV> tag that controls the panel has a z-index value too low. If you set the CSS z-index property of the tag to higher values (at least +1 than the DIV with the screenshots), you should solve the problem.
I hate CSS !

For those that don't know how to clear you cache in FireFox here are the steps:
