I tried that this a.m. and it didn't work for me. One, it's not listed in "add remove programs", so I had to go to "add remove windows components", removed it(or so it seemed), then dl'd IE6, dbl cliked it and it said "you have a newer version of IE installed already" and quit. Guess I'm stuck with it now.
btw, as much as I use firefox I must say it can't handle uploading attachments in yahoo mail. Why? Who knows, but when I MUST upload attachments in yahoo mail I MUST go to IE.
