   disable mouse movement with touchpad
  HiI need to use a touchpad as a tapping device (just detecting clicks on the pad) but not as a complete mouse substitute; so I would like to disable mouse movement only with the touchpad but yet allowing regular mice to move the scene (camera is linked to mouse movement).Do you know if this is even possible?   
  OS? Anyway, on Windows you may be able to get it working by reading raw input, by filtering messages based on which device send them. You will probably have to make a device specific solution.;  Windows, but what you say might just be way beyond my capabilities
