Hey guys, I've recently bought a vivotab note 8 mainly for taking notes on the go, drawing sketches. My main problem with the unit is that the ctrl key sometimes get stuck(?). I have no idea how and it happens random times, 90% of the times i didn't even pressed the button. When I'm hovering the pen, there is the little box beside the cursor with Ctrl written in it, and i can't click on anything. It happened both with windows 8 and windows 10 (even after a clean install).
