Thanks for your help. Unfortunately it didn’t solve my problem completely. Now I get a blank page where the product listing should be on the homepage in IE7 and IE6. The * My Account * My Wishlist * My Cart * Checkout * Log In links also drop below the silver bar in FireFox 3.6.3 but Opera 10.5.1, IE8, and Chrome display the page correctly.
Quick Search now works correctly and displays results when searching in IE7 but not in IE6. The link to the Advanced search page now works in IE7 but in IE6 the Advanced Search form lands at the bottom of the page.
