    <p>Thank you Dennis.  Unfortunately, I still just get the error
      message, so apparently it's something peculiar to my machine.  I
      wonder if there could possibly be something wrong in the way I've
      configured NCL? <br>
    </p>
    <p>I could update to the latest version of NCL.</p>
