I am having a repeatable problem in running Windows 7 using PD 8.0 in Coherence mode on a 13-inch MacBook Pro, Late 2011. I am running this at my desk connected to an external monitor. I regularly have to disconnect the laptop to take with me to meetings. All of the open windows in both the Windows 7 and Mac OS consolidate to the single laptop monitor just fine when I remove the cabling from the laptop. The problem starts when I attempt to connect the laptop to any other video display after this. I have attempted to connect to meeting room monitors and projectors as well as the original external monitor back at my desk and encounter the same video problem each time. The Windows 7 application windows will not show on the screen properly. They are either completely blank or partially filled in. I have tried to close out of all open applications and relaunch them, but the same problem remains. I have tried locking the Windows 7 machine and re-logging in as well as logging out completely and logging back in. This did not solve the problem. If I exit Coherence mode the screen "draws" fine. All application windows appear fine. Should I then go back into Coherence mode again, the problem returns. The only sure-fire way to eliminate the problem in Coherence mode is to restart the Windows VM. Are there any known solutions to this or work-arounds? Thanks JMic
