Sorry to say this but your site took AGES to load especially in IE7!
Invalid CSS and I am not sure about if it is a valid HTML or not. Still loading after 2 minutes...

Please validate your website by going to [Validate CSS] or [HTML/XHTML Validation]
Most of the time, you will solved most of your problem by validating them first!

If you problem related to CSS, you better read this sticky notes!

Cheers...
