> Hmm.. autoraising at the wrong time... You mean Firefox 3?
Oh Firefox 3 definitely popped into mind as I was writing that. It's usually pretty well-behaved even when I stress it with 10+ windows and hundreds of tabs, but maybe once every few days it does get confused and go on a brief auto-raising focus-stealing rampage.
Some of the older versions were much worse; I can recall having to kill the X server to get things unstuck.
