Walter,
>How about, Doug Hennig, Rick Strahl, Kevin mc Neish ? AFAIK they fall into the spcified category. I'm sure there are a few others.
I don't have access to their personal finances, so I can't tell you the answer. Maybe you have financial data that I don't have.
I do know that every VFP tool vendor I have talked with is also involved in software development. Often the tools were developed in response to a need found during a software development project.
You can have the last word, if you wish. I don't have time for endless debate.
