Hey Dave,
Yes - as stated in my original question because I thought for sure you guys would ask so I was proactive lol......I am on a Mac. I am seeing the extensions when I open Finder and go to a Folder where I keep these Word documents.
So I tried what you suggested, and the "show all file extensions" is not a ticked box.
Interesting.....not every doc started showing the file extension. Those that do - are not docs I have opened recently or done anything with for a long time.
As well, when I try to rename the docs individually now.....so I remove the extension, hit enter, it then flashes the extension back at me again, and then a small icloud icon on the document icon flashes quickly - which then takes the extension back off again.
