No luck. But it helped me narrow down the problem somewhat as the cursor movement wasn't so erratic when I slowed the sensitivity from 1.0 to 0.25. It seems that in Windows, the Wiimote Whiteboard program uses the left top corner as some sort of starting point for movement (X:0, Y:0 if you will) .. the game on the opposite uses the right bottom corner as the starting point for cursor movement, and this is why the movement is so much offset to the lower right. Plus, as the sensitivity is not exactly the same as desktop sensitivity, the movement doesn't follow my finger linearly. Ilya, I need your help on this one!!!
