My kid has a Wii. I finally figured out how to sync the red buttons so the nunchucks will work. But now every so often the nunchucks don't work and I have to re-sync it. Does this happen to everyone else? I would think you would only have to do this with a battery change. Ours seems to every other day to un-sync itself and since the kids don't know how to do it, I'm always being called to fix the Wii. What is going on?:) :)
