I have bought a Microsoft tablet pc and I love its pen style touch. In just 5 days now this is creating problems. I don’t know why but the application menu is not operating using pen. I have changed the handedness setting (left- or right-handed) in Control Panel and it is not showing any effect. My test hardware is a Motion C5 Tablet PC with Windows 7 Enterprise. I can easily access it with mouse then why it is creating problem by using pen?
