This answer is to make one Tkinter Window pop up overtop of other Tkinter windows.

In my app I have a large window toplevel which calls a much smaller window top2 which initially appears on top of toplevel.

If user clicks within toplevel window it gains focus and smothers much smaller top2 window until toplevel window is dragged off of it.

The solution is to click the button in toplevel to launch top2 again. The top2 open function knows it is already running so simply lifts it to the top and gives it focus:

def play_items(self):
    ''' Play 1 or more songs in listbox.selection(). Define buttons:
            Close, Pause, Prev, Next, Commercial and Intermission

    if self.top2_is_active is True:
        self.top2.focus_force()     # Get focus
        self.top2.lift()            # Raise in stacking order
        return                      # Don't want to start playing again
