Afternoon Update, July 25, 2016
I shut the computer off for some morning errands. Getting back on in late afternoon, I checked out the OneNote issue. I had my Quick Notes notebook open when I shut the computer down in the morning.
When I started the computer sure enough the issue was back and I had to go through the steps again of closing my Quick Note notebook and shutting down the Quick Note icon on the taskbar then restarting OneNote. Then everything worked again.
I also discovered that once I closed the Quick Note icon it was not coming back like I reported on earlier.
Upon starting OneNote with my Quick Note notebook closed and Quick Notes working, I let the Quick Note icon start up and left it running to see if Quick Notes would stop working. It had in the past.
I did some work in OneNote and went back and checked Quick Notes (bottom left side of the program) and it was still working.
I then opened and closed OneNote several times letting the Quick Note icon start up each time and stay running. I discovered that Quicks Notes continued to work. Whereas in the past Quick Notes would
stop and go into the 'Loading" mode if Quick Note started up (the icon one).
Some have said here that closing your Quick Note notebook worked for them for a work around. It seems it does now for me-at least for now. And yes, as suggested I created a new Quick Notes notebook
and pointed OneNote to it.
