I meant to email you that I found solution. The glossary is set to full page and has hierarchy even if you align your button to bring to front of page. So set the glossary to smaller and make sure it does not overlap the button.
Now I am having a problem with an error message, after trying to use the advanced setting in quiz question, 'Presenter is experiencing a problem with presentation. Try saving your work to another powerpoint and restart powerpoint. If this doesn't work...come here, I did save to a different powerpoint but it did not work. It won't let me save changes to quiz anymore and the font is all messed up.
Deb, did you post a separate question for the new error issue?
No but I will. I was able to copy the body of the presentation to a new power point and then import an uncorrupted quiz from another file.
