1. Create a main glossary on a course, default settings. Add one entry with concept/name 'test' set to auto-link. 2. Create a secondary glossary on a course, default settings except that the format should be 'Entry list'. Add an entry with any name and a value which includes the word 'test'. 3. Go to the secondary glossary's main page. Click on the entry. EXPECTED BEHAVIOUR: Entry correctly opens in the current browser window. ACTUAL BEHAVIOUR: The entry unexpectedly opens in a new browser window. (This is terrible usability. You're in the glossary itself, things shouldn't be popping up all over.) You get links to the glossary entry which are normal links, but there's an onclick which takes you to the same link with popup=1 in a new window. 4. In the popup window which shouldn't have opened, there is a glossary underline (from the main glossary) on the word 'test'. Click this word. EXPECTED BEHAVIOUR: Glossary popup for 'test' from main glossary appears (within the same browser window). ACTUAL BEHAVIOUR: Spinning cursor effect appears, but nothing happens.
