I'm not hugely impressed with IE7, but atleast I only use it when I check my email. Anybody else had it just randomly close any windows you have open? How bout having 3 tabs open, clicking to close 1 and it closes all 3? Doesn't seem to do it with only 2 open, but any more than that and it closes all.
It's too bad they didn't copy firefox's quality when they copied their look!
