TD freeze in perform mode

Im having issues getting a Windows comp (projector) working. Extended monitors are correctly configured in the Windows and Nvidia control panel yet when opening the Windows comp parameter to monitor 1 the image appears on the projector but the system always freezes. In Windows Placement the primary (designer) monitor is set to the left with perform mode (projector) to fullscreen. Has anyone come across this issue and a fix?
Thanks
Jonathan

I should note, no error message appears, the system only freezes as if ‘enable edit mode’ in the Windows Placement Dialogue is checked, which it is not.

Is “Perform Mode” selected in the Window COMP? This causes the main window to stop redrawing, which allows for much better performance.

Ah Malcolm, that worked! Thanks, case solved!

Also the Draw Window toggle in Window COMP will freeze or unfreeze the perform.
