So you are saying that the do-while loop is never exited, is that it?
If so, could you step inside move_it_by_lines and see why it doesn't
(move, that is)? It is supposed to move one line down.
Also, can you show the text through which this loop is supposed to
move down? If that text is displayed on the screen, are there some
unusual features it uses, like invisible text or continuation lines?
