Thanks to those who responded.Several good ideas and suggestions. You can open your WF 2 config.win in your WF4 and it seems to work ok. I didn't want to do it that way since I had customized a bad setup back when I started here and never fixed any of it. So I wanted to start over fresh.
As some suggested, what I did was open one session of pro/e with the config.win that I want to start from and open a separate session of pro/e and load my old config.win in that session. Works great. Then you can use copy button image in the old session and paste button image in the new session. Flawless transfer of the icons I wanted to save.
