Here are some directions for allowing pop-ups from forums.anandtech.com for some of the more common pop-up blockers.
1. Google Toolbar: Once you are in the forums simply click the amount of pop-ups blocked to cancel blocking for this page.
2. SP2 RC1 Internet Explorer: Tools Menu, Pop-Up Blocker, Pop-Up Blocker Settings, then add forums.anandtech.com to allowed pages.
3. Firefox .5/Mozilla 1.6: These Mozilla based browsers will allow the pop-up since it is a requested pop-up. (Shamelessly ripped from
CTho9305's post.)
4. AdSubtract Pro: In the control panel click Block in the left pane. From there add forums.anandtech.com to the Bypass list.
Not hard!

I've done the above for FireFox (which BTW 0WnZ0rZ IE IMO) and I don't have any more problems.
