New submission from Terry J. Reedy <tjreedy at udel.edu>:
Win7, 3.2.2, python -m turtledemo in Command Prompt Window
After running clock example, hitting Stop results in following:
Clock face, including hands, is erased. Day and date are left (intentional?), and the following appears back in command prompt window.
Exception in Tkinter callback
Traceback (most recent call last):

Demo continues to run.
Paint: Left clicking mouse moves dot without painting. Right clicking changes mode so left clicking draws line. It also causes some filling of enclosed regions. This double action is slightly obscure. The prompt on the bottom of the screen says "Use mouse/keys or Stop" As near as I can tell, keys are inactive. So prompt could delete '/keys'.
Module doc strings that explain each demo should be wrapped so that they appear in the code window without scrolling. Or the left window could be wider, especially if the user widens the window. 800x600 screens are pretty rare these days.
'Wikipedia' is a poor name for something just because it happened to be there. 'Rosette', for instance, would be better.
