A touch occurs next to the point touched, not at the point of touch

If you suspect that the touch screen is not functioning properly, go to the Windows desktop and move your finger across the screen. If the mouse pointer moves directly under the tip of your finger, touch functionality is working correctly. If the mouse pointer moves more than half an inch (1.3 centimeters) away from the tip of your finger, you should clean and calibrate the screen. To do so, with the computer off, spray glass cleaner onto a soft, damp cloth and gently wipe the screen to remove dirt and smudges. Do not spray cleaner directly onto the screen.
If touch functionality still does not appear to be working correctly, follow the steps below to calibrate the screen.
  1. In the Windows Start screen, type Tablet PC Settings to open the Search charm, and then select Tablet PC Settings from the results list.

  2. On the Display tab of Tablet PC Settings, click Calibrate.
