Cesar,
  Disable the 'xdriver' program, it is interfereing with VMD.
You can re-enable the xdriver when you're not using VMD if you need
to use the Spaceball with other programs.

VMD contains its own spaceball driver and doesn't need to use
the xdriver. It directly communicates with the Spaceball over
the serial port.

Thanks,
  John Stone
