Sorry, I forgot the cc option. This is my answer:

Yes, there is a solution. Instead of using TtaSetDocumentAccessMode(doc,0), 
you have to trap all 
modification in the document and let Thot performs only those which concern 
form fields.

It's easy to do that: 
a) In HTML.A you remove all events ElemNew, ElemPaste, ElemDelete, 
ElemTextModify,
   ElemChange.
b) In HTML.A you add in DEFAULT section 
        ElemNew.Pre -> NoEdit;
        ElemPaste.Pre -> NoEdit;
        ElemDelete.Pre -> NoEdit;
        ElemTextModify.Pre -> CheckType;
        ElemChange.Pre -> CheckType;

c) In HTMLactions.c you write the functions
/*----------------------------------------------------------------------
 -----------------------------------------------------------------------*/
#ifdef __STDC__
boolean NoEdit (NotifyElement *event)
#else /* __STDC__*/
boolean NoEdit(event)
     NotifyElement *event;
#endif /* __STDC__*/
{
  return TRUE; /* don't let Thot perform normal operation */
}

/*----------------------------------------------------------------------
 -----------------------------------------------------------------------*/
#ifdef __STDC__
boolean CheckType (NotifyElement *event)
#else /* __STDC__*/
boolean CheckType (event)
     NotifyElement *event;
#endif /* __STDC__*/
{
  elType = TtaGetElementType (event->element);
  elType.ElTypeNum = HTML_EL_Form;
  elFound = TtaGetTypedAncestor (event->element, elType);
  if (elFound != NULL)
    return FALSE; /* let Thot perform normal operation */
  else
    return TRUE; /* don't let Thot perform normal operation */
}

  Irene.
