It doesn't make sense because the wxMiniFrame is activated, yet I
still must click *a button* first.  Clicking on the wxMiniFrame
anywhere else (title bar, background, etc.) doesn't change the focus
at all, and key presses remain ignored.  But as soon as I click a
button with the mouse, the key events are handled.  Furthermore, this
was only the case under GTK; both OS X and Windows handled key presses
without having to "prime" the wxMiniFrame by clicking on a button.
