Windows Color Scheme incompatibility?

Has anyone else seen this message when activating Perform Mode?

“The colour scheme has been changed to Windows 7 Basic.
A running program isn’t compatible with certain visual elements of Windows”

And my project/Touch sits on a black screen until I quit it manually.
Ive had this project for ages so not sure why I am starting to get this.

I just have a standard aero theme (which eliminates tearing).

For me this only occurs if the windows takes up the full resolution of the monitor. If I make it 1 pixel less wide or less high, Aero stays on.

So I think that’s a workaround for now until I can figure out why windows is disabling Aero when the windows resolution = the monitors resolution.

oh, so set my comp to run a custom size (full, minus a pixel either way)?

Yup
