In mouse.c:mouse_poll(), Sdisabled, Sopen, Soff, Son enum.

In sys/cold/qcom.lisp: MOUSE-CURSOR-STATE ; 0 disabled, 1 open, 2 off, 3 on

   Since we talk about mouse... why are there 4 cursor states not only
   show/hide ? Disabled, open, off, on

Where do you see that?

       Another perspective. Setting the X/Y either in IOB only or both in
       IOB and A-MOUSE-X/Y causes the mouse pointer to behave
       strangely. When only the A-MOUSE-X/Y (and IOB X/Y to zero) is set
       like now in the code, it works OK. So there is something going on
       but I didnt get the full story.

    That is most probobly because the difference of mouse_x/y (the IOB
    registers) is what matters and not their absolute individual values,
    while A-MOUSE-X/Y are relative to the whole screen.
