When I play archery, the z-button releases at random times no matter how tightly I hold it. It's REALLY annoying. Has anyone else had this problem? I'm using a motionplus attachment. So far I've tried: A different nunchuck (still happens) I noticed the motion plus has a broken catch on one side, so I cannibalised a broken one and fixed this. Closed the curtains to eliminate any light interference. I haven't tried another controller yet or another motionplus (because I don't have one) but my suspicion rests on the motionplus.
