Breaking my own "rule" I have read this subject-less message. Since the PIC list has so many messages I usually just bin these, along with one's with attachments. I take the view that if a poster can't be bothered to supply a sensible subject line (by that I mean more than just "help me", e.g. something meaningful (so I can tell if I can probably contribute a reply) such as "16C74 locks up at power on - automotive") why should anyone be bothered to read it and if appropriate, reply to it?
