When I was playing with the input.device strange and "diabolic" ideas crossed my mind. In the spirit of display hacks "Mischief" was created. It is the ideal tool to scare beginners from using the Amiga ("There's a ghost in the machine!"). I don't want to tell you what it does, consult the program source code if you really want to know about it. But be sure that none of the actions "Mischief" makes are destructive. Still you have to be careful with windows you drag around. If anything begins to act strange, drop the window as soon as you can. Olsen
