Windowed Mode Mouse Lock / Capture (Window Mouse Capture) *TIP*

[Sir ChickenFunker]

This is how I force my mouse to stay within the window. What you need is called "Window Mouse Capture" its a oldie; but works for me on Win7.
Hope this helps you!

To Use.
Open WMC.exe it will make an icon in system tray. In the game window hit "F7" key. (You can change it if you want) Then you are Locked in; Hit again to Unlock.
