Okay, I have downloaded the latest version. I have always enjoyed this program over the years, and I always contribute money when I put it on a new computer. However.....I have only scratched the surface of what it can do. I need some better instructions. I downloaded some instructions, but they were from 2008. Where would I find the latest instructions for using PAINT.NET?????? Thank you, I truly do like this program.......
