<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>
<br>
