I still think it's much more likely the error is due to my misconfiguration than a bug. I think I've seen something like this before, just can't find anything in mail archives. I'll try asking on @current list. thanks again anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423
