Here's a nice little popup blocker.....

http://toolbar.google.com/

This is one of those little tools that someone told me about that I was a little sceptical about at first. But once I went to a website that I knew had a lot of popups, I was thouroughly impressed. And now, I wouldn't be without my Google Toolbar. It's so easy to use, and best of all......IT'S FREE!! If you get a lot of popups and don't have some kind of popup blocker, this is the best one I've found.
