sorry! a few releases of the touchscreen firmware ago, the max number of touches quietly went from 2 to 4. full positioning is still only accurate with just 2, but the touchscreen will attempt to keep track of 4 if they're separable in at least one axis. so there's nothing special for a program to do (i.e., no raw data to fetch). i haven't experimented with the feature much, but gonzalo has the beginnings of a nice little piano playing activity floating around somewhere. paul =--------------------- paul fox, [email protected] _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)
