Like Martin, I don't see that, on linux with a CVS Emacs from 2005-04-05.

Can you try the following
emacs -q

then evaluate following code in *scratch*
(setq pop-up-frames t)
(require 'info)
(Info-goto-node "(emacs)Copying")

for me when I M-x eval-buffer the *scratch* buffer is replaced by the 
Copying node. *info* does not appear in a separate frame.

If you get different behaviour, then this may be a bug in Emacs. If you get 
the same behaviour as I do, then we need to dig a little deeper.
