It is ;-)  As a matter of fact it's the combination of

(1) a bug in Emacs 23's `pop-to-buffer' causing it to _not_ reselect the
    selected window when it's used for displaying the buffer, and

(2) a recent change which had `find-file' use `pop-to-buffer' instead of
    `set-window-buffer'.

Hopefully fixed now (the bug in Emacs 23 remains unfixed since noone has
complained about it yet - after all `pop-to-buffer' was supposed to use
any but the selected window).

Thanks for complaining, martin
