Hm. It works fine for me (under Linux) as long as I click to close the
correct window. Perhaps the version of Tk that runs under Windows is
getting confused by the fact that you're calling Toplevel() with a
master widget argument. It doesn't need one (though it doesn't
complain under Linux either).

When I run your code with from Tkinter import * above and

def main():
  root=Tk()
  A(root)
  root.mainloop()

if __name__=="__main__":
  main()

below, I get two windows. One that Tkinter opens for free and the
second one as a result of the Toplevel() call. If I close one, the
program exits and if I close the other, I get "testing....".
