Game instantly loses focus with New Big Picture Mode if you (accidentally) press the Xbox button

Since the new Steam BPM launched, it is no longer possible to disable the Xbox button from trying to open the Steam overlay during gameplay. This is an issue with UWPHook as if you accidentally press the Xbox button during gameplay (easy to do), you completely lose focus from the game and it goes back to the Steam window. UWPHook essentially needs to disable the Xbox button somehow whilst running.
