I always see Parallels 9 (on OSX 10.9.3 as the host) not being able to wake up a suspended OSX guest. The screen goes black, but only sometimes I manage to get a login dialog on that screen. Most of the times the screen is simply black. Suspending the VM and waking it up again leaves it still black, while the mouse is captured. I need to shutdown the VM and restart it, which is annoying if you've left some apps open. How can I perhaps as a workaround assure that the VM won't ever suspend???
