Excellent question. I normally keep a notebook next to the computer and record exactly where I downloaded things like this. But I slipped and did not make a record. I am pretty sure the author is a familiar name on the 3dgs forum, and that it is not a new contribution. I can't find it in a forum search on the name, and the ZIP file has nothing about who made it. I am really embarrassed, but I can't remember.
Thanks for your suggestions.......
