BrokenMouse

In the eventuality that you enjoy playing retro games or simple ones that include map scroll, then there is a good chance that you notice the mouse acting up, especially if you are using a multiple monitor configuration. Simply put, if you move the mouse to the edge of the monitor, then it does not stop there, but rather go to the other monitor.
BrokenMouse is a tiny tool designed to address this issue and stop the mouse at the edge of the screen. Since you gain control over the mouse behavior, you can also avoid the unpleasant situation when the game loses focus and gets minimized when clicking on that case.

Automatically clips the mouse inside the screen

The application comes with a simple interface that displays the current mode and informs you of the current focused window. The program is designed to act as an automatic mouse clipper for old games, so you do not have to bother with the configuration. You can check out whether the clipping is enabled or disabled in the lower section of the interface.
Then again, if you are multitasking, the application comes with manual support where you can specify the clip to monitor. In addition, you can assign a hotkey for this purpose so you can toggle the clipping as necessary. You can assign a key from the Settings' window. Other noteworthy options that may come in handy include blocking WinKey when clipping is enabled, using aggressive clip mechanism and refreshing clip continuously.

A handy utility for controlling the mouse in multi-monitor configurations

All in all, BrokenMouse is a nice utility to have for anyone playing old video games on multiple monitors. Not only does it let you focus on your games and disable the annoying Windows Key, but it also prevents having the mouse move to another monitor.
