It's been a while since anyone has supported NESS. The last version I was aware of still had a couple of systems that didn't fire. Let me know if you ever find something. I have used it extensively for the last 10 years and think I pretty much worked them out. It really is the cat's meow. Make sure you get the manual too, its located here http://members.dslex...ers/markmorris/, it's invaluable. The tutorial is based on 8.1.1 and has good ideas and examples. It also has some bugs though.
