no other window

no other window

[Robert J. Chassell]

Today's GNU Emacs CVS snapshot, Mon, 2007 Jul 16  10:38 UTC
GNU Emacs 22.1.50.73 (i686-pc-linux-gnu, GTK+ Version 2.10.13)
started with
    /usr/local/src/emacs/src/emacs -Q -D
and with
    /usr/local/src/emacs/src/emacs -Q -D -nw

Starting yesterday and today's snapshots of Emacs, I could not get
other windows, just the one.  

That is to say, 

    `C-x 4 C-f' (find-file-other-window)

acts like 

    `C-x C-f' (find-file)

Saturday's snapshot works fine.

I could not see anything wrong with the recent changes to src/window.c

This first occured yesterday, 15 July 2007.

Yes, it does; I am writing in a new instance now.  Many thanks.
