You didn't tell us whether it works for you "in general". If you work
with two frames for "some time" does `redirect-frame-focus' what it is
supposed to do? If it doesn't we have a strange situation where, citing
from Ito's comment in bug#11513,

so Windows OT1H handles key input passed to a frame that is not in the
foreground and OTOH doesn't pass key input to another frame even if
explicitly asked to do so.

That's what we have to find out.

I suppose my example was just silly. Maybe you should try again with
(let ((old-frame (selected-frame))
(new-frame (make-frame)))
(redirect-frame-focus new-frame old-frame))
I don't know anything about `redirect-frame-focus' and can't test it
reliably here because I'm using special autoraise-frame settings which
likely interfere with any such focus redirection.
