Prevent controller input when window isn't focused?

[Paradroid]

I want to play another game on my 2nd screen while I'm waiting for lobbies to fill in PSO, but at the moment I can't because even when the other game is focused PSO is still reading the controller inputs.
So does anyone know if there's any way to prevent this behavior and make it so that PSO doesn't read controller inputs when the window isn't focused?

Yeah.

Open the instance in a VM, just be sure if you ever use two PSO clients this way you use the classic drop style so you don’t get banned for duping drops but since you are playing two entirely different games this won’t effect you.
