It is a place to start.  I am sending the reply to you as well as the 
list because I need more information and don't know if you are reading 
the list.  Please send responses to the list and not my email.

I am guessing that you are not registered with our tracker, 
bugs.python.org.  I can post these issues there, but need more info to 
do anything.

Unfortunately, tk, tkinter, and hence IDLE are the most troublesome on 
Mac, but they are the least well tested there.  Which of the two 
installers did you use.  Have you used previous versions of Python and 
IDLE?  If so, which, and are these problems new for you on 3.7.0?

If you start python and IDLE with 'python3 -m idlelib' in a terminal, 
and repeat the actions reported below, do you see any error messages in 
the terminal?

What happens if you run 'python3 -m test.test_idle'?
If there are any errors, please run 'python3 -m test -v -ugui test_idle' 
and report the specific error messages.

This makes me think that the problem is with the new version of tcl/tk 
installed with python or its interaction with tkinter.  Neither of these 
have been touched since last September or Octover.

Please run 'python3 -m idlelib.configdialog'.
After the unittests repeat, an 'htest' (human-judged test) box appears. 
Follow the instructions.  Does [cancel] hang the test?  Do any error 
messages appear in the terminal?

Repeat with 'python3 -m idlelib.help_about'.

Repeat with 'python3 -m idlelib.calltip_w'
