I'm getting a black screen and I have to suspend/resume the VM to be able to work again. It happens when I'm doing as follows. - Working with MS Access 2010 in Windows 7 in full screen mode. - I switch to OS X 10.9.4 (different space) and work there for a few minutes. - I return to the VM and now the screen is black and I can't get it back to normal. - After suspending/resuming I get the normal screen and I'm able to work again. The energy settings are the default Parallels settings (never sleep, never dim screen). Is there a solution for this annoying problem? I'm using the latest Parallels Desktop for Mac version (Build 9.0.24229).
