The splash page is a little bit too long, there's a scrollbar. On the homepage, the stuff in the iFrame is a little bit too wide, there's a horizontal scrollbar. Also, there's a very noticeable seam between the graphics on the homepage, it looks as though something is too big and stretching the table more than you intended. You provide no iFrame alternative, I'd suggestion one. I'd also suggest scrapping the IE proprietary mouseover filters in favor of regular rollovers.
