I am using macOS Mojave 10.14.6 and Python 3.7.3. I was running some turtle programs which then worked. Subsequently, I installed anaconda-navigator 1.9.7. After which, if I ran a turtle program such as below, I would get a blank screen (black) for a few seconds, after which I would be logged out.
# SquareSpiral1.py - Draws a square spiral
import time
import turtle
t = turtle.Pen()
t.pencolor('green')
for x in range(50):
t.forward(x)
t.left(90)
time.sleep(30) # sleep for 30 seconds
Is there any way to make turtle graphics work with anaconda-navigator?
