Well, I don't have a firm opinion on this, but yes-or-no-p is an active
function, here.  We always leave the minibuffer as the selected window
for this function, certainly when we've a normal minibuffer in the frame.
Why should it be different when we've got a minibuffer-only frame?

Also, the mechanism by which NF gets the focus in the bug scenario
appears to be random.  When the focus starts out in NF and we do C-x C-c,
the focus moves to MBF.  This is inconsistent.

The place where the randomness takes effect is the 

    Fredirect_frame_focus (gfocus, frame);

in do_switch_frame I drew attention to yesterday.

See above.

You might, yes.  But I think the irritation in having to switch frames to
NF to look at the long list will be outweighed by the opposite irritation
of always having to switch frames to MBF to answer "yes" or "no".
