How could I debug this issue? just a guess from a quick glance in bkchem.py: in the if __name__ == '__main__' part of your code you have something like this: myapp.geometry(geometry) myapp.update_idletasks() myapp.deiconify() myapp.mainloop() myapp.destroy() In the following minimal example: from Tkinter import * root = Tk() root.mainloop() root.destroy() when you click the "X" button in the window corner to close the window, you will get an exit code 1 along with an error message like this: Traceback (most recent call last): File "test.py", line 6, in <module> root.destroy() File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1858, in destroy self.tk.call('destroy', self._w) _tkinter.TclError: can't invoke "destroy" command: application has been destroyed Maybe something like this is happening? If yes, the solution is to add a handler for the responsible window manager protocol, as in: from Tkinter import * root = Tk() root.wm_protocol('WM_DELETE_WINDOW', root.quit) root.mainloop() root.destroy() Best regards Michael .-.. .. ...- . .-.. --- -. --. .- -. -.. .--. .-. --- ... .--. . .-.
