```
import tkinter as tk
tk._support_default_root=False
from turtledemo.__main__ import main
main()
```
currently fails at line 165: `pane = PanedWindow(orient=HORIZONTAL, ...` with `RuntimeError: No master specified and tkinter is configured to not support default root`. Since all other widget calls include a master argument, adding 'root' here fixes the failure.
