I made the mistake of 'upgrading' to IE 7. Now, I can't make it do ANYTHING if I type an address into the address box. It just sits there. I have to open up a IE 6 window, type or copy the address in there and THEN it opens the website.... in the IE 7 window. OMFG! That's not just annoying, that keeps me from going anywhere NEW without using IE 6.
And we won't even dicuss IE 7 failing to find my Favorites file about 50% of the time.
