Welcome to our community, kfrdk
The Glossary Hotspot Wizard works in a very similar fashion
to the Smart Index Wizard. Both are a bit like shooting a gun. It's
something you simply run from time to time to make sure all is
updated.
As you have seen, changing a definition in the Glossary
editor area will not automatically update the definitions in all
the topics. To do that, you need to run the Glossary Hotspot Wizard
again after you make changes. Then you will have the opportunity to
update all the expanding hotspots to include the new definition.
