     Could you explain this a little more, I not sure I follow what you're
saying.  If you have a horizontal single pixle width line, it would be on the
screen every other 1/60th of a second interval.  (I might be wrong but I
think you meant that each half-frame comes in every 1/60th of a second).
What I'm trying to ask is: no matter how many times you display a half frame
before the next one comes in, won't that horizontal line still be on the screen
only every other 1/60th of a second interval?

  Excuse my comments if they seem stupid or have already been said, because
I kind of dropped in the middle of this debate and missed the earlier messages.
