I always find it amusing how many "IE-only" sites work just fine in Firefox if they don't know it's Firefox. Don't know, though I tried adding something to cart in FF, and it just gave me a blank cart and a "sorry, there's been an error" popup. Curious, I started following the trail: the bottom of the page says "powered by SnapShopPro", which leads to visicomscientific.com. The front page didn't have SnapShopPro listed, so I went to their products page, which suggests there isn't much hope for getting their cart out of IE6 requirement any time soon...http://www.spinnwebe.com/temp/visicom.jpg Incidentally, Safari doesn't even get a warning, though the error's the same. I guess when they wrote this, they didn't even know Safari existed.
