Office Notification reminders popup window disappeared

[Michelle]

I had my Office Notification reminder popup window appear on my Mac. I left
it unattended for awhile without dismissing the window. Suddenly it
disappeared and it will not reappear. It's NOT minimized in the dock and
it's not set as "hidden".

I even entered a new task and set the reminder for now so that it would
hopefully force the window to pop-up. No luck. I hear the beep showing
that the reminder is activating, but it doesn't show on the screen.

How to I find where it's hiding?

I got it back by quitting Office Notifications and then restarted it. Not
sure where they disappeared, but restarting ON brought it back easily.
