One serious bug has surfaced in SPECX6.2, which means that some maps are ``unopenable''. The program starts to open them, and then falls over. A kluge which fixes this in some cases is to open another map first, then open the offending map afterwards. However the only real fix is to replace the incorrect routine. Any site which has problems can obtain a copy of the routine direct from me, or from John Lightfoot at ROE (REVAD::JFL).
