Hi again, Nulsonmandela,
Thanks for the log and follow-up!
For some reason, even the Beta isn't working for some users. We'll add your report to the list of ones that have gone awry. The senior staff is aware of the problem, and working on it.
The only thing we might suggest as a work-around, is to roll back to previous video drivers. But, we're not certain how effective that will be. You may just need to sit tight. They ARE working on the issue.
cheers,
