Are you all also using ATI drivers? (which seems to be where the issue is...unless you guys aren't...then it's a whole different problem..)
Yeah I've got ATi here, I don't think this is a driver issue. When I had the conflict with WB6.1 and Catlayst 8.3 Kris Kwilas sent me an email replying to my support ticket telling me they had narrowed it down to an issue with ATi's drivers, and temporarily fixed the problem until they do. Once I installed the update this bug started happening. I replied to the email and was told by Kris that it probably wasn't an issue with the fix and that something may have been broken in 64 bit. That was Sunday last week...
And Karma, I'd just ignore him. He's like an old school resident troll that apparently was never thrown from his bridge.
