I saw the topic of this thread and IMMEDIATELY bought two new nunchucks just in case mine becomes ill. In fact, it was acting kind'a wonky but new batteries in the remote solved the problem. I'm very nervous/cautious with those little knob/rotating thingys. Broke one on an Atari - it was getting a lot of use. So, I tend to look at those things with a jaundiced eye. Back ups!
Damn it! I KNEW it! From my fingertips to the gods' ears!!! I no sooner typed the above and my nunchuck 'c' button dies!!!!! I can't believe it!
Ah, whoops! Operater error. I'm going to go hide now.
