I noticed that you are using GoLive and ImageReady....
..any chance you could get hold of Dreamweaver to output your code?

...no biggie... the code would just be a little cleaner and lighter is all

Also, a little css-p would help you out a LOT too

The scrollers work fine for me on my Windows IE (latest), but like
was said above, the spacing for the nav buttons on the left are slightly off a bit.

Good luck, and Great concept!
