You said in your LQ post that you upgraded to 3.15. Phoenix's website says that their latest is 4.0R6.1. Maybe you should give that version a try.

This is probably my last post for tonight, hope things work out for you.
Thank you, and everyone else very much.
I love getting into problems like this on the computer. When the problem gets solved, and it WILL be, I will learn something new. Many thanks to all of you for helping it happen.
