Thanks LynB for the F7>F8 to Deselect solution.

Been trying the Escape key and like you said, sometimes it works and sometimes it doesn't.

Also trying to click around outside the selected area is very hit and miss and usually results in another selection.
A universal 1 click Deselect for all windows would be GREAT!!!

PLEASE PG, it would make a great XMas gift for the next upgrade:)
