Well,that question is real simple answered.I bought it cause the PR before that was good, the patents were claimed and it looked like a good thing to do. But like you say in your messages always ... we are all just guessing. Seems i guessed wrong. And besides that , i think it's for the same reason you are in this one also ... or is it just because you love the KSWJ-charts ? Again i think you deserve the nobel-price for being the most optimistic person ever :o)
