Hello, I'd like to create a grid of lines ( forming 9 fields) on top of all other visible windows ( on the desktop ). The purpose is to create a "mousegrid"-application to control my mouse pointer via a remote control by clicking 1-9 representing one of the fields. When a button on the remote is pressed, the selected field divides up in 9 new fields and thus I can control where to move the mouse while repeating the procedure. The big question though is how to draw the grid on top of the desktop covering everything else and still being able to see through the grid so I'll know where to move the mouse. Thanks!
