When setting up the Cintiq 13HD touch as an extended display the cursor doesn’t appear on the Cintiq. What do I do?

Go to the Control Panel on your PC or Preferences your Mac.  Select Display. Change the Cintiq 13HD touch to primary display and the cursor will appear on the Cintiq. If the Cintiq 13HD touch is setup as an extended display then it isn’t usable.
