Hi, my cursor jams to the bottom right of the tv screen and stays there. I have tried re-syncing the wiimotes, works for about 5 minutes. Borrowed wiimotes and sensor bar, same issue. I can use all other buttons on the wiimote when the cursor is frozen - doing my head in. How does the wiimote communicate with the wii? Could the wireless chip in the wii be fried? Cheers.
