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?

the only way to fix is for the game to lock on the cursor to the monitor on which it is being projected – Sathya Aug 6 '13 at 17:45
Anyway I can do that? 'Cause the game doesn't seem to. – Xade Aug 6 '13 at 17:47
You can simply disable the second monitor if you want to avoid a software fix. But programs should handle this on their own if they don't its a bug. – Ramhound Aug 6 '13 at 18:08

It's really up to the game devs to implement the cursor lock so that the cursor doesn't go out of the current window - although you can use tools like Actual Multiple Monitors to lock the cursor to the current monitor.

I've used that feature succesfully quite a few times, so it should work.
