Thanks greg,

	This is how I have *fixed* it :-)

	if ((stat = system_call(buffer, SH, TRUE)) !=0 ) { 
	  dprint(1,(debugfile, 
		  "System call failed with stat %d (edit_the_message)\n", 
		  stat));
	  dprint(1, (debugfile, "** %s - %s **\n", error_name(errno), 
		error_description(errno)));

	if(errno!=1)
	{
		ClearLine(LINES-1);
		error1("Can't invoke editor '%s' for composition.", editor);
		sleep(2);
		return_value = 1;
	}
	else
	  return_value = 0;
	
	}
