Working with Tkinter is like trying to dig through fossils. So much out
there is old or incomplete. It's like the Tk species went extinct. The
trail seems to end in 2005. I think I read it's not quite dead, and a
newer looking is coming.

This gave the same results:

As I thought this over, while on a long walk, apply might not be the
place. That is, if pressing OK gets you to apply and the code discovers
how do you get back to the dialog. I think you may have answered that
below with the validation code.
