Bad gameguard update?

And yeah, definitely, IE is pretty terrible. You'll be better off using basically anything else. Many of the features added into IE lately are longstanding features of other browsers even. I'm quite sure that IE because FF has such a large share of the market now, and to be honest, tabs was the number 1 draw to FF for me.

On the other hand, Firefox handles tabs poorly, and has been stealing its features from Opera..
