  11. Mark,
  12.  
  13. To make the scroll bar move in "chunks", I think I would override
  14. PROCEDURE TFrame.ScrollBy(delta: Point; invalWholeFrame: BOOLEAN)
  15. so that it will do the following:
  16.  
  17. 1.  Recalculate the parameter "delta" to constrain the position of the scroll
  18. position.
  19. 2.  Call "Inherited ScrollBy" withe the recalculated "delta".
