I am using Emacs under Windows, and I downloaded supposedly development 
version which includes AUCTeX with latex-preview. It says it is "GNU 
EMACS 22.0.50.1 ... of 2005-10-18." I read in CVS README that 22.0.50 
seems to correspond to 21.3.50, and 21.3 is the latest in the "windows" 
directory.

I discovered that Emacs under Windows sometimes scrolls back and 
sometimes does not. To the best of my understanding, it does scroll back 
if the point is at the end of the file. If there is even a newline after 
the point, then it does not scroll back.

I also tested this on GNU Emacs 21.3.1 under Linux and it worked fine.

By the way, even under Linux, when the word which made Emacs scroll is 
very long, then after moving this word to the next line Emacs positions 
the point (at the end of the word) centered horizontally on the screen, 
which means that the left edge of text is again beyond the window. I'd 
like to always see the left edge unless the point is out of window. Is 
there a way to achieve this?

I am writing all this because I did not find a way to make Emacs follow 
the conventional line-breaking behavior of programs like Microsoft 
Notepad, Mozilla Thunderbird or even Pine. In all these programs the 
line is broken when it becomes longer than a certain bound. I could live 
with Emacs waiting to break the line until I press Space if it would 
scroll back all the way left. I also tried longlines and maniac packages 
but they seemed to interfere with AUCTeX and/or fontification (I can't 
tell exactly at this point).

Any opinions about this?

Thank you again,
