what have you learned recently?

can your mouse go offscreen? if it can, do you get an offscreen position? is there a way for the code to change the mouse position.

years ago a friend of mine made a program that took over the mouse and window manager so that every time you click on a window it would move them around so that nothing was under the mouse. if he was around today i'd suggest he do it for the mouse hovering over a window, too.
