Hi James,
I noticed that when 2 wiimotes are activated it sometimes gets in a mode that uses more than 4 points for calibration. It is possible to force more than 4 calibration points on the OSX version of the whiteboard by default?
it’ll only show more than 4 points if one of the Wiimotes doesn’t “see” the whole screen; this is intended for covering a large screen with two Wiimotes. More than 4 calibration points won’t give you better precision or any other advantage when using a single Wiimote. Read section 4. at the wiki for more information.
Sorry for the late reply.
