Our computers updated to Windows 10 last night, and now our touchscreen will not recognize the location of the spot we touch. When we touch the right side of the screen, a blot on the left side appears. When we touch the middle of the screen it does recognize that it has been touched. We have tried recalibrating, going through the process of touching the crosshairs as they move through the process, however, we do not get the option to select Apply when we get back to the Recalibration window. Thanks for any help.
