I'm using Microsoft Word 365 MSO (16.0.12730.20252) 64-bit on Windows 10 Pro Version 1909 (Build 18363.836). For the past month or so, I've noticed while editing that Word will unexpectedly switch from the Home Ribbon to the Draw Ribbon.
I've tried various means to understand what triggers the switch; I've even videotaped an editing session. One thing that seems to trigger a switch is a Windows 10 Notification (toast) with an image in it. But it doesn't always happen with a notification, and sometimes it happens when I'm sure there hasn't been a notification.
Has anyone seen this annoying behavior? Any idea how to stop it?
