I recently got around this problem as follows

Easy solution: If the Tkinter app doesn't need any special code run when the
window is closed do nothing and DO NOT call mainloop() from your Tkinter app
(while in IDLE, outside of IDLE you will need to add the call again).

Solution B:

Write a close() method and have it be called by any cancel buttons as well
as doing a master.protocol("WM_DELETE_MESSAGE",self.closeit).

Then
def closeit(self):
    self.master.quit() #exit out of this mainloop()
    self.master.destroy() # actually close the window

In the first solution IDLE will actually be fully functional while your app
is running.  In the second case idle will not be fully interactive until you
close your app down.
