I just looked at your site in IE7 and FireFox.

There are some issues with overlapped items and repeating images.

Your site looks skewed in both browsers.

#navMainWrapper
{background-color: #989da3;
font-weight: bold;
color: #ffffff;
padding-top: 1px;
padding-right: 1px;
padding-bottom: 1px;
padding-left: 1px;
background-image: url(../images/Cart_bar.gif);
background-repeat: no-repeat;
Try changing background color to transparent.

Suggestion: Visit your stylesheet for some elements that are not functioning/missing. In FIreFox some areas that should contain stylesheet info are returning the message "no Sytle Information"

I hope this helps you.
