Almost there getting everything to work but still having issues with the IR pen not working properly. I am using one of the Economy Pens purchased from Wii Teachers.com - can do calibration no problem but the pen action is eratic at best and mostly no response. Have used various surfaces (projector screen, wall, physical whiteboard) and have changed postion of the Wii controller to various distances and angles. Still the same results. Once calibrated, I have had tracking utilization results ranging from 37% - 51%, and still the same eratic pen action when interacting with the board. Suggestions most welcomed.
