When you go to assign a stick function, you must hold the joystick exactly centered and very still. The centering dead zone is quite small which makes it real sensitive to center. It took me a few tries, but once I got it to recognize it, it works great.
Unfortunately, with XP you can't install the sidewinder software to adjust the centering dead zone.
On win98 you can reduce centering sensitivity which makes it easier to set up.
