I noticed that 'oing' did NOT like me pulling the screen down!  One or
more of the sprites would become a semi-solid bar moveing back and
forth.  It looked very similar to what the old Atari 800 did when you
turned on a Player but did not clear out the image memory.  BTW simply
dragging the screen back to the top put everything back to normal.

I also noticed that you could pull the screen down alittle more than
half way before things got strange.  Could this be a fall out of a
dma pointer being changed while sprite DMA is enabled?
