Glossary Entry display mode :: popup window displays too many elements.
This is not a new 2.0 issue, and it is related to
Whenever a glossary hyperlinked word is clicked, a popup window should open which should only display the entry and its definition. That popup window should not display the full shebang of the current moodle course. This feature has been asked many times in the past, and I have had to provide workarounds to make it work in 1.9.
Moodle 2.0 (or 2.1) should be the right time to solve the problem, which seems trivial. See attached screenshot.
