    i hope i do not annoy anybody by posting again, but i am afraid my last
    message was not noticed by anybody.
    is there something i don't know but should ? as it seems the problem is
    still existing.
    i would be happy do test whatever is needed to trace the problem.

    please respond.
    regards
    -alex
