BrokenMouse

BrokenMouse is an application that makes it impossible to move the mouse cursor outside the main monitor. This is useful for gamers who have multiple monitors, as it allows them to play games without interruption due to the mouse cursor moving off screen.

How does BrokenMouse work?
BrokenMouse automatically detects programs and games running in full screen mode. Once a program is detected, the application will prevent the mouse cursor from moving outside the selected monitor. This means you can play your games without worrying about the mouse cursor moving to a second monitor.
