I have actually had this problem happen to me, but it never dawned on me as to what was causing it. The guys at Jeux-France noticed something very odd during some playtime with Red Steel. Their pointer on the screen started to jump back and forth a bit, making it very hard to aim. They weren’t too sure what the issue was, until they realized that they had a bluetooth microphone in the room as well. It seems that other bluetooth devices can cause varying degrees of interference with the Wiimote. Now all I have to do is find out what bluetooth devices are near my Wii…I’m looking at you PS3!
