Exception in Tkinter callback when quit life game

[liudonghua]

I tried to run the life game via freegames play life. When I click close button of the game window. I got Exception in Tkinter callback.

> freegames play life
Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\Liu.D.H\AppData\Local\Programs\Python\Python311\Lib\tkinter\__init__.py", line 1948, in __call__

           ^^^^^^^^^^^^^^^^

The exception comes from the following code.

free-python-games/src/freegames/life.py

Lines 53 to 61 in cfa331f

 def draw(): 
     """Draw all the squares.""" 
     step() 
     clear() 
     for (x, y), alive in cells.items(): 
         color = 'green' if alive else 'black' 
         square(x, y, 10, color) 
     update() 
     ontimer(draw, 100) 

And I can catch and pass the exception to make it work.

I am using miniconda in a macbook. I replicated the error. When I click the close button I got a similar Exception in Twinker Callback:
