I've been testing out IE7 ever since Microsoft released the public beta. There are a few things that need to be fixed with the JS/CSS code I've developed. I hope to address these issues in the next few weeks.
On top of these problems I noticed there were issues with the main AAAS template. The left-side expandable menu navigation was failing horribly and completely unusable. Luckily the fix came to me easy enough as I noticed one of the library functions, the publicly available lib_bwcheck (which hasn't been updated since who knows when), was not detecting IE7 correctly. A quick fix and everything was working like normal.
I've passed the information on to KG.
