Black Hole

May contain traces of nut
Something on the site is causing by browser tab to flicker - maybe an advert issue or something. My other open tabs aren't doing it (IE8).
No flicker here. Mind you I do have Ad Muncher and Adblock plus running so don't see any adverts anyway. (FF v8.0.1)
I've ended up having to reboot, all sorts of funny things started happening (and IE is the first thing that goes flakey when my system needs a reboot).
