    Hello Lindley,

    Thank you for your reply. I did saw your post of december in fact.
    My point was rather to wonder why it worked with a former version of
    ustsuw and not anymore.
    The parameter NMXEBN is inchanged in the 2 versions.
    Anyway, I have now two solutions to resolve that issue.

    Regards.
    Sebastien.
