Hello, I am evaluating Parallels Workstation.. My host machine has three monitors: a-the laptop screen b-a screen connected thru the HDMI port of my laptop c-a screen connected thru an ENCORE Usb-To-DVI adapter I want to use the three screens while i am in full screen mode, but Parallels only seems to work with the first two monitors... It seems that parallels doesn't work with a second video card, is it because it is an usb videocard? EDIT: I am running Parallels Workstation in Windows 7 (host) and my guest is ubuntu 11.10. thank you very much
