Do you remember when you played Pacman how you could go off the edge of the screen, and almost magically you would popup on the other side? You can setup your computer mouse to do the same sort of thing. When you touch one edge of the screen it automatically jumps over to the other side.
All you have to do is download the free Edgeless software, and go through the small installation process. I tested it out, and it works like a champ. I’m not sure whether I’ll keep using it since I quickly started to realize how often my mouse touches the edge of the screen. The result is that my mouse often inadvertently jumps to the other side of my monitor.
If you have an exceptionally large monitor, however, this could minimize how much you have to move your mouse to get from one side to the other. ;)
