If your pen tablet is malfunctioning, do the following:
(1) Connect your pen tablet to a different computer. If the pen tablet functions properly then the issue is a “driver conflict” with the system file or application.
(2) The pen tablet LED light should indicate a malfunction. Pressing the pen tip on the pen tablet should activate the LED light on your tablet, this indicates the hardware is in proper working order.
With the pen placed away from pen tablet area press the pen barrel button, if the LED light is on, this indicates the hardware is in proper working order.
