I'm no Tkinter expert -- far from it. But I would assume that
GetPassword, as a subclass of Dialog, creates a new window, and thus you
have no need for the root window. root.withdraw() hides the root window
from view, and allows the application to continue running. I imagine
there are other ways to accomplish the same thing.
