Hi I have a MacBook Air running Parallels 9 on it and I am connecting it to a Thunderbolt display. Now on a regular Windows 7 pc laptop, you can connect to a monitor and under Control Panel<Display<Connect to a Projector you can choose to extend the desktop to an external monitor so that you can drag programs to the secondary display while doing other things on the laptop display. Now I would like to replicate this behavior for my Windows 7 VM on the Mac. I have connected to the Thunderbolt display and it extends the Mac OS. I can start Parallels and put it into full screen and duplicate it to the Thunderbolt display, but I can't quite find a way to put the Windows 7 desktop on the Mac and extend it to the Thunderbolt display as I would on a regular Windows 7 pc. Has anyone accomplished this? Thanks!
