    <tt>Hi,<br>
      <br>
      It should be ok, but in your case the TH will not benefit from the
      dialog module (you do not use it) - all the info to he hidden will
      be appended to the Contact hdr (as extra param), while when using
      the dialog support, this info is stored into the dialog.<br>
      <br>
      To be honest, I never tried the combination of nathelper and TH
      _without_ dialog support. But give it a try...if you get a trace,
      I can check if ok.<br>
