WiebeTech today introduced Mouse Jiggler, a new hardware solution to prevent a computer from entering sleep or screen saver mode while users work, or while they are away from their desks. Mouse Jiggler is portable and automatic with no software to install or run. It simply plugs into any empty USB port and goes to work instantly. Mouse Jiggler is available in two versions, each priced at US$29.95. Both are available now.
