	I have a popup shell in my application which contains a dialog
	widget. The label of this dialog widget is set (using XtSetValues)
	just before popping it up in a callback routine, and the
	string displayed varies.

	The trouble is that the XtSetValues() is completely ignored after
	the first call - the label is set once, and does not change, even
	though I've checked that the string I'm using is actually different.

	The code fragment is given below:

	void  callback(w, client_data, call_data)


	....................
	{

		..................

		if(n_vector != 0)
                        sprintf(buffer,"Nearest match is %s, \n%f units away\0",
                                        best_match, min_dist);
                else
                        sprintf(buffer, "Database is empty");
	
                n = 0;
                XtSetArg(wargs[n], XtNlabel, buffer); n++;
                XtSetArg(wargs[n], XtNsensitive, TRUE); n++;
                XtSetValues(client_data->dialog1, wargs, n);
                XtPopup(client_data->popup_shell1, XtGrabExclusive);
		..................
	}



	Any help is greatly appreciated.

	Thanks in advance.
