[issue17822] Save on Close windows (IDLE)

[Terry J. Reedy]

Terry J. Reedy added the comment:

If I open Command Prompt, and start Idle with
C:\Python\Python33>python -m idlelib
I get the same attribute error without the Shell window closing. Perhaps not having a console to write the traceback to closes 3.3 but not 2.7. Peculiar.
