I just got it too but I was using IE 6.0. This is a nasty bugger. Even when you click on the "no" or "cancel" buttons it acts as if you clicked "ok". Funny though, this is the first time such a thing has happened to me. I always have a popup blocker on and I see popups here at the Org only a few time a year, so this bad boy was rather startling. I'm rather aggitated about it at the moment.
