Why do people keep referring to the speed of light? In what I learned of electronics, signals are carried by electrons travelling round in conductors (and semiconductors). AFAIK electrons are quite a bit slower than photons. -- Cheers John Summerfield Microsoft's most solid OS: http://www.geocities.com/rcwoolley/ Note: mail delivered to me is deemed to be intended for me, for my disposition. ============================== If you don't like being told you're wrong, be right!
