Paul:

Thanks a million. This was exactly what I was looking for, and had not yet found - a hole between version 1.1 and 1.2. I had not found this change in code. Now everything makes sense and behaves and builds and runs. And, as of today, we have the upgrade and version 1.3. Life just keeps getting better!

Many thanks for spotting what I just couldn't see.
