That must be the difference. The catalog on the CD says version 1.2. I hadn't paid attention to that before.



Here's what it says:

"Version 1.2 Changes

For this CD distribution of the catalog I have added some additional 

html coding.  The flowcharts have much enhanced graphics and a couple of new instruments have been added since the last release.  In particular have a look at the brandnew main group 70.  

Thanks to the many people who have encouraged my work in the past. I hope you will all continue to find good examples for learning and teaching here. "
