Hello there, I am running Parallels Workstation (6.0.13976) on a win7 laptop, running win8 as a guest. The native res of the laptop is 1366x768, but the win8 Parallels VM insists that the full screen resolution is 1024x768. Therefore when using full screen, I'm forced to use the host in 4:3. (There are 2 black bars on either side of the screen) I've uninstalled and reinstalled the Tools. Whilst uninstalled, the screen will stretch to fit the screen (at 1024) - but during the Tools installation process, it will revert back to 1024x768. There's no option for 1366x768 in the guest OS. Regards, Mick
