        I believe we are not communicating. Your analysis (forward
declaration & all) is correct. You do have a log of errors. I just do
not understand how you caused these errors to appear. IOW please post a
complete code snippet which cause these errors to appear.

        Once again, this will have to be resolved, and I will abide by the
final recomandations.
