If you try to close it grabbing it at the knob, you bend it outward, which prevents the screen to go into the rear slot. Push it from the front end of the screen, that way it closes completely. Funny, isn't it? In other words, the screen is too thin and bends.
Generation V or so of the future electric CX will possibly solve that with the then optional premium screen package :-).
