Someone is using my computer when I am not around, and while I'm "ok" with that, I'd like to do a little tormenting so they ask me permission first. To that end, I'd like practical joke ideas. I used to have a program that would move windows away from the mouse, and if I could find that again I'd be thrilled. But anything else would do, from hi to low tech. Obviously I do not want to damage my computer, nor do I wish to comprimise the privacy of the person in question. Thanks all.
