Yup, I've the same problem as Cohen. Though it's a recent development, this blue screen upon zoning thing... Didn't have a problem until after the system message about Mhaura and to get the hell out of there. It was after that, when using the 'porter in Windurst Waters and again zoning into the Moghouse from Windurst Woods that I received the blue screen of complete frozenness. I'm not coming back for a few days, to see if they've fixed this problem.
Note: I may have dual screens on a laptop install, but I don't have Windower, so it's not that, at least.
