I have used mouse without borders successfully to control several pcs.
But I don’t know how to switch screen : it is possible with some hotkeys according to this video http://www.youtube.com/watch?v=fQuwtduvwGA but I can’t see anywhere what hotkey it is.
Update: hello, I’m talking about viewing screen from computer 1 ON computer 2 a bit like remote desktop not about moving the mouse to the other computer. The video shows it’s possible.
You can configure ShareMouse to switch monitors only if you hold the
CTRL, ALT or SHIFT key. While moving the mouse cursor near the monitor
