Hello!
I have exactly the same problem of Fatima << after calibrating, When the pen is used the pencil image (icon) is about 2-3 inches from where we place the pen point.>>with the ActivBoard, I tried upgrading the firmware of the board with ActivManager but without success. Therefore I ask where you downloaded the firmware, since I have already updated the driver.
I’m Sorry about my English because I am Portuguese.
