The touch screen is not operating correctly.

Calibrate the touch screen.

Enter Configuration mode and select Terminal Settings>Input
Devices>Touch Screen>Calibration.

On PanelView Plus CE devices, you can also open the Touch control panel
application and select the Calibration tab.

The calibration requires four user screen touches. When the touches do not
converge to a satisfactory calibration, you are asked repeatedly for additional
screen touches; the calibration process never terminates.

A touch screen that does not calibrate is not present or not functioning
properly. Replace the 700 to 1500 display module or the 400 to 600 terminal.
