That's very strange because Emacs 22 and 23 should not be
different in the codes handling that kind of thing.

I'm not sure.  That may solve the gnus case, but there will
be another code that uses select-frame in the similar
situation.  I think we must first find why only Emacs 23
doesn't work well.
