My ActivSlate 60 sends the board into calibration mode every time I touch the surface.
Thanks for posting.
Please can you confirm which ActivDriver you have installed on the computer?
This can be found by launching ActivManager and choosing Control Panel and the driver version will be shown at the bottom of the window that appears.
What happens when you calibrate the ActivSlate, does this then repeat the calibration mode when you try to use it?
What model of ActivBoard are you using? Can you help to confirm the firmware version of this too (found in the ActivManager Control Panel).
