I think the major problem is, that with the 3DConnexion SpaceNavigator
the camera/molecule is moved rather than the usual scaling that is
usually done with the mouse wheel.

Is there a way to interpret a forward/backward movement of the device as a
scaling rather than a camera/molecule movement?

Best regards,
