A lighthearted thread, but one with a real question. Right now, it is impossible for me to have a toy of my own, since just about everything I have, my son wants to play with. That's especially true if there are games to be played. While I try to keep my new toy away from him, sometimes it is the better part of valor to occupy him with some game, if it is hex-a-hop or Angry Birds. Problem is, twice I've come back and he's erased the desktop with all my games. Last time he also managed to shut down most of the desktops. It was bad enough that I had to restore from a backup. So, how do I lock up these settings so that my son doesn't muck with them? It is really a pain in the butt when either I find stuff on the desktop that I don't want or even worse, when stuff disappears.
