I did not use the SL4 for along time and when I switched it on again, the touch screen did not respond any more to the pen.
I have done a hard reset but it did not help. I am now caught in the calibration programe of the display. When I touch the screen with the pen, the cursor moves but always comes back to the center when it has moved aroud all corners. When pressing Esc of the virtual keyboard to escape this programe, there is not reaction.
Has anybody a solution?
Thank you in advance for your help.
