    Yeah I think I have an idea of what the basic problems are,
    but I'd have to understand things better before I know if I
    am really on the right track.

    My idea would probably also involve redoing some of the code
    code too, so at the moment I don't think I have time. If your
    simple fix works though, then that sounds good.
