Hello, About 10% of the time as I lift my finger up the x or the y value changes e.g. from my printf statement status=fffc0000, x=135, y=46 (similar numbers repeated a few times) status=fffc0000, x=136, y=47 status=fffc0000, x=74, y=113 status=0.x=0,y=0 Have others seen this problem ? any suggestions ? (yes I can always through away the line before status changes) thanks yash
