I have already scoured the forums and called Wii tech support with no luck, so I'm hoping someone has heard of this type of problem before.
I've had my Wii for about a week, and most thing work great, except for some reason, the cursor is extremely jittery in the Mii and Photo channels. The cursor continually blinks and when I mouse over any button the controller vibrates in quick pulses. In all other channels and in games it is fine. Also, in the Wii settings screen, when I press A once to select something it often clicks twice on whatever I'm trying to select, like a letter of the keyboard or a "next" button.
When I called tech support we tried everything, removing all other light sources, smacking it etc., and they said it would be a few weeks before I could get a replacement, so I'd really like to fix this on my own. It's not a huge deal as the internet channel is fine and I really only use the mii channel when a friend or family member is going to play (the channel is usable, it is just very difficult). The strange thing is that it only affects certain channels, and I have tested this extensively. I would really appreciate some help!
