Problem displaying

Hi Gerkin,
Very nice looking plugin – one we hope to make use of. We could not get the tooltip to display if we use a glossary term.
To check it we used the standard wordpress theme / clean install, but still can’t get it to work.

I can provide login details. Can you assist?
Thanks
Luke
