Answer
When applying your screen protector to your Trimble Yuma 2 tablet, make sure you do not have any raised edges around the outer portion of the screen protector. A calibration of the screen needs to be done once a week even if you are not having issues. The calibration can be found if you go to Start , Control Panel ,  Tablet PC Settings then Calibrate.
