Someone please help me with this program.  It is the stripped down
version of a level editor to be used in the design of classical
tile-based games.  Included with the source code is the level data and
graphical tile set that the program uses to build the level.  All this
program does at the moment is scroll around a tile map and that's
where the bug is.  It uses page flipping to update artwork in the
background and give the illusion of a smooth scrolling screen.
However, it only scrolls smoothly when moving left or up.  Scrolling
right or down is choppy....as there is a brief pause after every
second page flip!  Could someone please look at this and tell me
what's wrong?

To run it, type EDIT with an argument of JOVA.
