I've never had this problem before:
I'm playing Red Steele 2 and now and again the stick on my nunchuk gets "stuck" in reverse causing me to move perpetually backwards. Resetting the wiimote fixes the problem temporarily. I've tried 3 separate wiimotes, 3 separate motion-plus controllers, and 3 separate nunchuks and they ALL have this problem. I've also tried different batteries (rechargeables vs regulars).
I'd like to find a fix for this as it's getting really annoying. I'd like to kick some butt without running away from my opponents, lol.
