I wasn't aware of the ability to write Python scripts for this purpose, thanks, I'll give it a try.  In the meantime, I am awaiting a controller profile to be used with ControllerMate which should open up the programming potential of the Space Explorer.

As for the Contour Shuttle Pro, I have been using one myself for Final Cut Studio but interestingly enough, its buttons are easily programmable with regards to Poser functions, so, why can't the 3DConnexion people get their act together to do the same?
