Help menu item causing unexpected behavior

Thanks Judy. The Help tab IS a built-in Player Feature.  But for some reason the Help and the Exit buttons (only) are not controllable via slide properties. 

Agreed it is unpredictable behavior and I will report it - just wanted to post here in case anyone (including staff) had opinions on the matter.

As far as creating a custom button, we prefer to use out-of-the-box functionality for things like basic navigation. Back in the day we built everything as custom functionality (using Toolbook Openscript). But over the years we found we were spending as much time tweaking and fixing and troubleshooting and adjusting such functionality as we were on good learner experience. We adopted the mindset of minimizing custom functionality except when needed for mission-critical requirements. We pride ourselves on robust and elegant custom solutions for those types of requirements, but stay out of the weeds of low-impact customization of basic functionality like standard navigation and page numbers and so on.  It's a matter of where you choose to spend your time. 

Thanks for the response and suggestions.
