Joystick direction as response & RT

[Nick]

I can certainly forgive it, but unfortunately that's not the problem.
I can get E-Prime to recognize the joystick and record certain
responses (e.g. button click and concomitant RT), but I can't get it
to record the direction of first movement and the RT of that response.
