Unresponsive hidden menu bar on Windows 8.1

Running VMWare Workstation 10.0.1 build-1379776 on Windows 8.1 in full screen mode with a hidden menu bar, about half the time I can't get the menu bar to drop down. All the waving around and clicking I try with the mouse up at the top of the screen does nothing. I'd say about half the time the menu bar is unresponsive, and I can't discern any differences between when it is and when it isn't. I also had the problem on 10.0.0, and hoped that there would be a fix in 10.0.1, but no luck. I never had a problem with this on Windows 8.0.

Any comments? Suggestions?

Thanks,

Tom
