[Tkinter-discuss] Correct order for dialog display

[Bob Greschke]

The .withdraw() should be right after the statement that creates the Toplevel window.  Creating it, then making the call to this def show() is giving the system time to make the window visible.  If the Toplevel() and the .withdraw() are together the window doesn't show up until the .deiconify().
