A family of Microsoft word processing software products for creating web, email, and print documents.
Thank you, Yves!
This allows me to work-around the issue.
I had to go to File -> Options -> Customize Ribbon, then select 'Developer' on the right hand side to show the Developer tab first before I could use your advice, but that's worked great now that I've done that.
Such a frustrating issue, though and still outstanding in Windows 10 build 1511 10586.1106 and Office 2016 MSO version 16.0.4549.1000 32-bit.
