It works now in Safari 2.0.4 Mac OS X 10.4.7 (the layout doesn’t break anymore)
But I have a strange problem with FF 1.5.0.7 for Mac : there is a big processor surge (all the way to 100%) when loading your page, almost crashed FireFox (and I have a 2,16GHz Intel Core Duo with 2Gb RAM...). I don’t know why... Anyone can confirm ?
After seing this, I checked, Safari does not suffer from the same problem, though the processor load rise to 36%.
Maybe from all the javascript in there...
And Heliotrope is right : way too much divs here... lot of cleanup to do too.
Rather than having 7/8 divs at the bottom of the page, place a background image it will be better.
Thanks for the capture stuff

I usually use browsershots but it take a bit of time to get the result...
