active window change when moving the window separator in a splited window

[marc dechico]

Hi!
In GNU Emacs 21.4.1 (i386-redhat-linux-gnu, X toolkit, Xaw3d scroll
bars)
 of 2006-03-07 on hs20-bc1-6.build.redhat.com
configured using `configure  --build=i386-redhat-linux
--host=i386-redhat-linux --target=i386-redhat-linux-gnu
--program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin
--sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share
--includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec
--localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man
--infodir=/usr/share/info --with-pop --with-sound'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: fr_FR.UTF-8
  locale-coding-system: utf-8
  default-enable-multibyte-characters: t

I could reproduce the bug just after starting the application:
You split the window 
You click on the bottom window that becomes active
As soon as you click  on the window separator to change the windows
proportion the upside-window becomes active.

So if you were trying to use page-up or page-down on the bottom window
you just get the next page on the upside window.
