I just downloaded DisplayFusion, and after a while with tinkering around I found out that I couldn't use Esc in Overwatch after preventing window deactivation.

After enabling it for the first time, Esc works while in game. However, after alt tabbing, moving to one of my other monitors and entering the game again, Esc won't work. I can press Esc to access the menu, but not for any other uses. Esc is bound as ''Back'' in Overwatch, and it won't work now. If I enable window deactivation, alt tab and enter the game again, it works perfectly, which leads me to think that DisplayFusion is messing something up.

Anyone who know how I can fix this?
