Using the following code, the root window will not close properly when the close icon is clicked:

from tkinter import *
rootWin = Tk()
l = Label(rootWin, text="foo")

Similar issue occurs with Tk.grid().

OS: Mac OS X 10.10.5
Python IDE: IDLE 3.4.4
tkinter.TkVersion: 8.5
tkinter.TclVersion: 8.5
ActiveTcl: 8.6.4

What do you mean with "properly"? All looks good to me on Linux.

Also note that installing ActiveTcl 8.6.x has no effect if the tkinter in use was linked with an 8.5 version of Tcl/Tk, as the one you are using apparently was. Make sure you have installed the latest version of ActiveTcl 8.5.x and try again.

I've reverted to ActiveTcl 8.5.18. Issue persists.

Uploading screenshots before and after attempting to close root window.

No problem on Windows either, where the minimum window width is wide enough to acommodate all 3 frame buttons (-  []  X).

Please run your directly, either in the terminal or however else one does so on OSX, without IDLE, to make absolutely sure that IDLE has no effect on the behavior.  (It really ought not to.)

Ran script on Terminal. The issue disappears, and everything works normally.

Running through IDLE, the issue returns. Sorry, Terry.

I was running from IDLE when I said no problem on Windows, so this is OSX specific.  Are you running same version of python  (splash message) and tcl/tk?  (on IDLE, Help => About IDLE).  Does Python on OSX have equivalent of pythonw.exe?  If you start IDLE at terminal and then run from IDLE, do you see and error message in the terminal?

It's almost certainly only found on OSX. I'm currently taking a Python class of approximately 150 students, and at least two of us independently found this issue on our respective Macs.

IDLE and Python are the same version (v3.4.4). The info window lists Tk as version 8.5.18, which matches the version ActiveTcl.

I'm not familiar with pythonw.exe as I've been using Mac.

Entering "idle 3.4" at Terminal opens IDLE as a separate app and Terminal waits until the app is closed. While running the script in the app, the issue persists.

If the problem is that the window is too small to contain the close icon, this is not Python issue. May be this is Tk issue or end application issue.

This occurs even when the window is large and/or packed with multiple elements.

I cannot reproduce this issue with Python 3.9 ( installer). 

Both with "Run Module" and in the interactive shell (both in IDLE) the window will close properly.  In both cases the window it too small to show the minimise and maximise buttons (as in the original screenshots), but that's not something we can fix on the Python side. 

I propose closing this issue as "out of date".

Unfortunately, I can reproduce it, or at least odd behavior when run from an edit window on with 3.9.0 on macOS 10.15. By observing the macOS Dock while running this, it looks like a second Python app instance is created while running this. We have seen similar behavior as documented in Issue38946. I have an idea what's going on there which I'll try to look at this week.  Let's close this as a duplicate so it's not forgotten.

I just reproduced this too with Airbook Mohave.  When IDLE's Shell is running, it is linked to an execution subprocess that is initially invisible, unless and until the user creates a visible window.  Tk() does this.  On Windows, a tk Window icon appears when I mouse over the IDLE taskbar icon.  On Mac, a new python rocket icon, also used for Python Launcher, appears.  And it becomes the active app for the Apple menu bar, making it more tied to the OS than on Windows.  In either case, I can switch between IDLE and tk windows by clicking icons or sub-icons.

When I click the red close button on the tk window, it disappears, but the rocket app icon is still there.  Clicking it maybe restores the window, which was hidden, not closed.  Or I may have to right click the rocket and then 'tk'.  Right-clicking the rocket and then 'quit' fails to close.  But trying to modify the tk window may fail with 'app destroyed' even though it can be made visible.  Closing the parent IDLE closes the Window.
