I've had the same problem on KVM's from Cybex, not frequently, but it has
happened, you might want to stay away from them. You should also be able to
kill the mouse daemon to reset it. Something like "kill -1 PIDOFMDAEMON"

Did you get a real KVM or just some rotary switch box?
If a switchbox, then yes, you will have problems since they do not
maintain the CLK/DATA lines to the computer they are connected to, so when
you do switch back to them, they will more than likelty be out of sync.
This is what a proper KVM is for. It maintains those signals to the
computers so you do not lose sync.
