I just updated Yahoo! Toolbar for Firefox (version 1.5.0.20071211). Now every time I launch Firefox, multiple windows open with the text "Entering yahooBuildToolbar". I'm able to close them faster than they open so I can eventually get them to stop, but obviously this is a problem. Anyone else having this problem?

I don't have an answer for this but the same thing is happening to me! Uggh. Will try the other person's suggestion though. Tomorrow. It's too late tonight / this morning...
