I am having trouble keeping my wii remotes working. I will put new batteries in and it will work great then after two or three uses it will stop working the wii remote still turns on but it doesn't light up and I can't use the cursor. I can still use all of the buttons and when i press the home button it shows full batteries. This started happening to all four of my wii remotes at the exact same time and it happens with every brand of batteries I've tried (Duracell, Energizer, Rayovac, and Interstate). Anybody know what is going on?
