Anyone know how to get the shift key to alter IGM? On the Pro it acts as ESC.

I've had the same problem - best solution is to use the sidewinder utility to map each button to a keystroke, and then use it as a keyboard, if you see what I mean. eg, up mapped to up arrow, shift mapped to spacebar etc.

It's not satisfactory, and the responsivity can be erratic with this method, but it works.
