Displaying a message box outside the main loop seems to mess up tk's
message dispatching somehow. One way to work around this is to use a
separate Tk instance and throw it away after displaying the message:
tk = Tk()
Button(tk, text="Exit", command=sys.exit).pack()
xxx = Tk()
xxx.withdraw()
tkMessageBox.showinfo("Test app", "Click on Ok, then on Exit.\n"
                      + "Do you still see the problem?", master=xxx)
xxx.destroy()
tk.mainloop()
