This only happens when I'm on 2+2. It's been happening for a few weeks nos:
Sometimes when I click on a new forum link or a thread link, or I even just click on a blank space on 2+2 - a place that shouldn't link me to anything - another tab will open to another page. The new page is usually some kind of poker site - or even a Facebook page for some silly poker game.
Any ideas how I can stop this from happening? I use an ad-block extension and have never had any issues with it before.
