Below is an example. If I do
$ python3 hello.pyw
and then type Alt+F, the File menu does _not_ pop up. If I then type
Alt+F a second (or subsequent) time it does.
It seems that Tkinter is ignoring the *very first keypress*. If I press
any key (e.g., Space, or x) and _then_ Alt+F, the File menu pops up as
it should.
