Hi
You can't since I think its meant to be used like a "ticker tape" and there is only a single line. You can make it as long as you wish but only the last screen width will appear. It would be better if it scrolled left when the screen was filled (and had sound)
BTW the Space entry problem is odd as I am trying to find the conditions when it happens. So far it has behaved correctly. But it definitively occurred.
