I compiled an ran the tablet example in the example/widgets/tablet. I use Thinkpad X61t tablet computer running Windows 7 professional. The window and canvas are shown, and the menus are working, but nothing is drawn. It looks like no tablet event is captured by the TabletCanvas::tabletEvent(). I tried QT v.4.6.0 and v4.6.1, and both does not work. I am not sure if I am missing anything.
