I thank you for the chuckle about the smiley faces.
Think of Word 2016 as version 1 of Microsoft Word. It's a completely different set of code from any version before it, so if you want to get your bugs fixed for posterity, now is the time to do it. After a few weeks, this window of opportunity will be lessened.
There is now a forum dedicated to the Office 2016 beta. If you have example files you would like to submit, please make a new question for each specific issue. Provide download links just as you did with the watermark problem. That was incredibly helpful
to me. I was able to see exactly what you were seeing. MVPs can forward your example files to Microsoft's product group.
Right now Microsoft is focused on hangs and crashes for Office 2016, but they want submissions of all sorts. Other problems, feature requests, suggestions, complaints - everything is on the table for Office 2016 and now is the best time to get these issues
aired.
