SEARCH PROBLEMS! The new search script from Google has been a real problem, it DOES NOT render correctly in IE9 (produces a huge blank light blue field), but works correctly in everything else. You may have noticed this odd blank problem recently on many ebay listings as well. There is simply no fix for it, so we have removed it from everywhere but the BOTTOM of the gateway page, so it does not destroy the page view. You may still have to turn on scripts each time you visit that page in IE (wow, what a freature...) This is VERY unfortunate, but there it is. Our apologies for any weird page problems it has created for you. Firefox or Chrome are certainly suggested by us as far more suitable browsers. Don't forget control-F within your browser searches the page you are on!
