Okay, I had another look at this problem I was having where I could only move one axis at a time with the Spacepilot Pro within MoI and it just so happens that all I had to do was hit the 'Calibrate' button in the 3Dconnexions properties window...duh!
All nice and smooth movements now, took almost a year to figure that one out :(

Thanks for your help Michael and Burr.

Cheers
