Twin monitor support on Desktop 9 with Mavericks

I recently installed Mavericks and have discovered a problem with twin monitor support. I am running Desktop 9, always in window mode with a Windows 7 guest machine. If I run the virtual machine on my Macbook monitor, everything is fine. However, if I drag the window to my external monitor and then close Parallels, the next time I start Parallels and my virtual machine I can't get to it. If I then disconnect the external monitor, the virtual machine appears on my Macbook monitor. I can then reconnect the external monitor and drag the window to it.

I have tried the obvious reinstall of Parallels but it's still the same.

Cheers,

Jeff

 

Hi Jeff,

Please (re)install Parallels Tools as suggested at http://kb.parallels.com/8969
