SetWindowsHookEx seems like a very powerful function, but I'm having a really hard time finding thorough documentation on it. AllAPI only includes the constant for keyboard hooks. The MSDN help has the constants listed (WH_MOUSE, WH_KEYBOARD, etc) but it doesn't give the values. I have a program called Mouse Wiggle that wiggles your mouse around. I want to be able to use the mouse hook to add some more features. Thanks.

oh yeah. If you guys download mouse wiggle, could you run it for a little while and tell me if the mouse has a tendency to stray in a direction on your computers? I think the decimal rounding is causing the mouse to stray.
