Mouse moves out of game onto other monitor while in game

[Plutoxes]

no matter weather i am full screen, windowed, or windowed border less, whenever i am in game and i move my mouse out of the screen far enough in the direction that my other monitor is, it goes onto the other monitor. this is bad because, if im In a mission and i flick, or just look left enough, my mouse goes out of the game(but im still in game still in game) then when i click to shoot while my mouse if out of the game, i exit the game and open the application that is on my other screen or just exit the game in general. i then have to click the war frame window again, or if im full screened, i then have to go to my task bar and open the application from there.
