Hi Team,

This bug is related to module = Tkinter , method = destroy().

Considering I am able to open below window and Project Deliver List is a button. 
When we press this button, below pop-up appears with which I am able to save my file.

Now, when we use below code for the first window:

root = Tk()
root.after(3000lambda: root.destroy())

If I am using this code on Mac OS, then on clicking on button ‘root.destroy()‘ command hold as it should. But on Windows OS, while I am saving the file, ‘root.destroy()’ destroy the pop-up.

Please look into this as I have to deliver this to client.
