I'm a little tired of your attitude towards people who are just trying to hold discussions so they can better understand the problems, even if they don't fully understand them initially. If you can't be bothered to take the time to do that then just don't reply at all instead of trying to put people down all the time. It seemed to me a reasonable question to ask why Giant in current doesn't degrade to the big lock we had before but your explanation does little to help me understand that. Fortunately, Bosko was willing to take the time to provide an explanation so now I understand better. -- Paul Richards
