I just did; seems it has something with server/client to do.

It works in emacsclient; not when running as ordinary process. Tryed
both as emacs -Q, and with my init file.

In Compiz; the newly created window does get focus, but the mouse is not
moved; if mouse is noved then focus switches again; but this did not
spooked. It seems that it has something to do if it is emacs or
emacsclient.

I don't know how emacsclient works; maybe it just does not pass all
requests to the server correctly?
