can't open the same buffer in a second frame

[ken]

It used to be nice that I could open the same buffer in a second frame
(aka window).  Sometimes I need to edit the same file in three or four
places and it's necessary to have all of them showing at the same
time... and for other reasons.  But I tried doing "C-x 5 b" and also
"C-x 5 f" yesterday and couldn't do it either way.  I could open a
different (not currently open file or buffer), but couldn't open the
same one.  It worked years ago. Why take away perfectly good and useful
functionality?  More importantly, how do I get it back?

I tried this here, and both "C-x 5 b" and "C-x 5 f" worked just
fine, though they both wanted me to specify the filename. "C-x 5 2"
opened a new frame and automatically displayed the buffer from
the previous frame.

I suspect that there is something in your ~/.emacs.el
configuration that is causing this. Best thing to do is do
a binary search of your configuration. I.e., comment out half of
the config and save it. Run emacs and see if the problem has gone
away. If not, comment out half of the remaining config and try
again. If it has gone away, un-comment the section you just
commented and try again. Rinse and repeat until you've found the
errant config.

Hope this helps.

Perhaps try first with "emacs -Q" to sidestep your whole local
config.

"C-x 5 2" worked... didn't know about it, and it actually does what I
need more directly and efficiently.  Thanks.
