Alphabar does not take user to glossary term

Hi - Using D6.11 and glossary-6.x-1.6.tar.gz (md5_file hash ok) Glossary is installed according to the Readme.txt in the module.
Thanks for this great tool.

Brief background: I created a new vocab called "Glossary" and have a dozen or so terms to start with.
These display beneath the alphabar on the same page - I enabled a navigation menu to the Glossary.
Terms are flagged in other nodes like FAQ and Book. Clicking on the flag takes the user to the term on the glossary page where the alphabar is.

I just have one issue as far as I can tell:
When the alphabar is displayed at the top of the page, one should be able to click on a letter and "advance the page to terms beginning with that letter." This does not happen. The page just reloads once and all alphabar letters are no longer hyperlinks.

I've only seen this reported once in this Issue list and the comments do not help in my case.
Our site is in early development, but is live here: http://ehs.wcape.school.za/help

Please, please help :-)
Cheers
