I figured this problem out. I've discovered that once Allegro calls
the do_dialog function, it just keeps on going through the dialogs in
it's free time. So, if in one of the dialog functions you are
displaying something, it will re-draw it every time it goes through
the dialog. I've solved it by only having it draw if a flag is set.
