After several days of mysterious mouse jumps, keys getting “stuck” on the keyboard and repeating over and over, and varioun non-responsiveness of my computer, I was extremely frustrated. I tried moving the wireless reciever five different places, re-compiling synergy, scanning for spyware, etc. Of course everything was fixed by putting new batteries in the wireless mouse and keyboard. Noticing a theme? I should get sponsorship from Energizer.
