This error started popping up on me about a week ago. I don't think it's directly connected to WM v6.1 because I've had 6.1 quite a bit longer. After a few days of this error popping up, I started making sure to not leave any Web browser on one of those automatically refreshing pages, not even in the background, nor on a background tab. Have had no problems since being careful with auto-refresh pages. Hope your problem is as easy to solve, though it seems not so easy.
