I am runnung code in Python Processing.  
Then I make changes.  
I am running again.  
The previous canva is still there. And I also can see the current canva.  
How can I get rid of old canva?

If I run Java Processing. I see only one canva with latest changes.

I use Python Mode for Processing 4  
processing-4.3

Hi Elena!

As far as understand, Python mode in Processing 4 is broken ☹  
Please try v3 in Processing IDE 3.5.4 if you must use it.

Otherwise, you might also want to try [py5](https://abav.lugaralgum.com/como-instalar-py5/).
