Help me review for errors - functionality only

Hi, I dont want any reviews on layout or cosmetic things, because the company has signed off on the design and I am tweaking it right now. What I want you to review is the functionality, like, tell me if something doesnt work.

I especially need help in testing in Vista, and in IE 6/7 cos i dont have access to them, and if you find an error if you know how to fix it it would be great :D


Anyway I know of the following problems:
- Video popup links dont open in IE6
- Lightbox overlay does not span full page

Please help the website goes live in 2 days.

well i tested most of the links in IE6, IE7 and FF and have not found any functionality problems :)... so far.

Thanks so much! That is great news! I feel bad about not asking for design reviews but I cant change it so its best to to start picking holes in it! Thanks Again!
