Hi Michael,
I don't know the correct behaviour, but you should create a clear
situation and delete one InputDevice. For the wheelmouse, the wheel
takes the function of the middle button on 3 button mice. The scroll
behaviour is triggered by 'Option "ZAxisMapping" "4 5"'.
Definitely the 'Emulate3Buttons' has to go then. My guess was that the
erratic movement is triggered by you inadvertently clicking both left
and right button...
Good luck,
