Query: Found at last!

I had a copy of this back in the 90's and lost it. I have been looking off and on for years, finally it turned up. Only problem is, it is not designed for XP and took quite a bit of research to get it to run. This is definitely the best source of information for young and old. It makes learning interesting and has lots of useful tools to interest young children. I use it to show how the solar system works and we can predict where stars will be at a future date and where to look for them.
