CursorLock is designed to limit cursor movement while user selected programs are in use.
It can automatically detect programs, or you can manually add them in. This type of app can be helpful for those using dual monitor gaming setups and lose the mouse off of the main game window during gameplay but can be utilized for most programs if desired.
CursorLock is simple to setup, and there is no configuration to speak of - unpack, add games or programs, and that is it. Simply minimize it to the systray when ready. Once CursorLock detects that one of the listed programs or games are opened, it will automatically hold your cursor on the active monitor. Need the cursor to move freely? Hit F11, and it roams free again.
