We have since discovered and confirmed
that changing the map scrolling settings in the program can fix this
issue.
After starting the program, go into the suitcase (in the
bedroom). This suitcase is just below the map. Click on options on
the lower part of the screen (It is between copy and quit). This
will bring up an option dialog box. Look for Map Scrolling. (Left
hand side of the screen, third item down. The default setting will
have a check to the left of Map Scrolling. Click on this, this will
turn the check into an X.
Now you will be able to move as many times as you want on the
map. The only thing that it changes visibly is that when you move,
the frame doesn't scroll down, up, etc, but quickly flips to the
next frame. It will look like it is turning the page of a book.
If this does not resolve your problem it will be caused by a
corrupt user file. If you start the game with a new user name the
problem should not occur
