Workaround for 1.8 driver not waking up
 

OS 10.8 driver version 1.8

Problem: If the machine goes into sleep mode, the USB device will be awake but the display will be blank. If you VNC / Screen share you will see all 3 screens, for some reason the driver is just not displaying.

Work around: Open any application that supports Full Screen Mode.. eg Preview. Switch to Full screen, the display will wake up again.
