Strange behaviour when moving cursor between lines |

Hi,
I am a longtime user of emacs on linux platforms. I recently installed emacs23
on my macbook pro (fink install emacs23) and see unexpected behaviour when
moving the cursor forward one line via CTRL-n. I'm not sure if this is a bug,
but at a minimum, CTRL-n does a different thing on a linux GNU Emacs 21.4.1
install than on my mac installation.
On my mac, when I open a file in emacs and navigate to the next line using
CTRL-n, the cursor does not go to the next line of text, instead, it goes to
the next row of text as displayed on the screen. For lines of text that do not
wrap, there is no difference between these two behaviours, but for wrapped
lines, there is.
For example, if a single line of text has wrapped on the screen, and my cursor
is currently at the first character of the line, then CTRL-n takes me to the
first displayed character on the second row of the same line of text (the first
wrapped row), but not to the next line as specified by a newline character.
While this may seem rather minor, it wreaks havoc when using rectangle cut and
insert (CTRL-r k and CTRL-r y).
Is this a selectable setting? A bug? A known difference between emacs 21 and
emacs 23? Something else?
I see the same symptom whether I start emacs in a new X window (emacs file.txt
&) or within the terminal window (emacs -nw file.txt).
Details of emacs on my macbook pro: GNU Emacs 23.1.1 (i386-apple-darwin10.4.0,
GTK+ Version 2.16.6 of 2010-07-23
Details of emacs on linux machine: GNU Emacs 21.4.1 (i686-redhad-linux-gnu, X
toolkit, Xaw3d scroll bars) of 2008-01-04 on norob.fnal.gov
Thank you,
James

This is a feature. See this entry in NEWS:
** The C-n and C-p line-motion commands now move by screen lines,
taking continued lines and variable-width characters into account.
Setting `line-move-visual' to nil reverts this to the previous
behavior (i.e., motion by logical lines based on buffer contents
alone).
I'm closing this bug report.
