Hi David
What you can do is to launch the Glossary Hotspot Wizard. (
Tools > Glossary Hotspot Wizard) With that, you can run it
against the selected term and it will trawl through the topics
looking for the term. You will then have a chance to update the
existing terms to match the new information.
Unfortunately, as you have seen, there is no dynamic link
between what is inside the Glossary and the expanding definitions.
Hopefully this helps... Rick
