I have just uninstalled IE7. It to was doing the same as yours. I even disabled all the add ons but no difference was noticed. From clicking on the explorer icon and actually getting on the web page took 45 seconds. With IE6 it was on within a couple. I just went into add and remove programs and uninstalled it there. The old explorer automatically took over and I never had to do anything to get it back. I liked the clean lines of the new look but the speed was dissapointing. I looked at a few forums but no help was forthcoming.
