Giving focus is part of the intended semantics of switch-to-*, so this
change in Emacs-23 is considered a bug *fix* rather than a bug.  If you
want to display in a new frame without selecting it, you'll want
to use something like display-buffer.

As for moving the mouse, it does seem undesirable, tho it would be
expected&normal if you've set focus-follows-mouse to a non-nil value.

Note that all the mouse movement and focus manipulation when creating
a new frame is terribly dependent on the window-manager (and its
configuration) and it is difficult to make it work reliably in all the
possible different cases.  So when reporting such problems, try and
provide as much info as possible about your window-manager so as to try
and make it possible for someone to reproduce the problem.
