Thank you for the compliment ComeOnPTK. I really don't have anywhere near the knowledge about the technology as others on this board do. I have had exposure to many different industries and perhaps I have a take on a given situation that may be different to others. I post what makes sense to me. I may be completely wrong but from bits and pieces of what is distilled here we may get an ingkling of what is really happening. Unless your statement was tongue in cheek and I missed the poke. It's all good, either way. All the best. Derek
