Just as the title says, I can drag my mouse over to my secondary monitor while playing some games. Not all games. For example, I am currently playing GTA 3 (practicing for a speedrun which makes everything 5x annoying) and I when I drag too far to the left, my cursor is showing on the other screen, but I am still in control of the camera ingame. If I then click, the game minimizes. Yes, I am running the game in fullscreen.
I have this problem when playing borderless (windowed fullscreen) in League of Legends aswell. But when I switch to "normal" fullscreen, it's fine.
I am also running Win7 64bit if that's any help. Does anyone know how to fix this problem?
