Ah!  Use the 'sleep()' method that comes with livewires --- time.sleep()
from the Standard Library actually interferes with the 'Tkinter' graphic
event loop, preventing it from redrawing the screen.


The fix should be easy: just substitute:

     sleep(...)

wherever you see:

     time.sleep(...)

and your livewires code should be fine.


Good luck!
