Sometimes I get PM's and I don't want to totally navigate from the forum to read them, and at the same time my popup blocker was not allowing them to open in a new window. But I was able to change the setting in my popup blocker to allow ONLY popups from this site to open. So it will block all the crap on other sites, but I can still read my PM's in a little window without having to navigate back and forth from the forum to my profile page.

The way mine worked was that I just clicked on my toolbar where it said POPUP Blocked and I had the option to always allow popups from this site. It's really handy so I thought I would share!!
