- I tried to answer your original question privately but it bounced.
-
- The answer, I think, is that there is simply a physical hardware
- limit on how high up in the video scan the sprite can start, and if
- you push the visible part of your picture up to that limit, you won't
- be able to have the sprite partially disappear above the screen.
-
- With less severe overscan, Ifind that I can move my regular spot-in-
- the-center cursor all the way up, but an application that sometimes
- gives me a pointer with the spot at the bottom has the effect that I
- can only slide it part way off screen at the top. I think the active
- spot that Intuition thinks the mouse is over goes all the way up as
- you keep moving the mouse, though you can't see that.
