Hi!
This must be a bug!
When a scroll a window by hold down the the down-arrow button,
the scrolling motion have anoying jumps now and then. What happes
is, obviously, that the window gets recentered. I have tried (nearly)
any combination of settings of variables in the customization group
"windows", but nothing helps.
Today I have tried the following:
Set scroll-margin to eg. 5. Press the down-key repeatedly (but slowly
so you can see what happens). Then the window is supposed to scroll
so that there are 5 rows from the cursor to the bottom of the window.
But now and then there is no scroll, so that there is only 4 lines from
the cursor to the bottom of the window! The next press of the down-key
brings things back to normal. There are no long lines in the file, and
and the behavoiur does not seem to be conneted to any specific points
in a file.
The problem occurs in
GNU Emacs 21.2.1 (i386-msvc-windows98.3000) of 2002-03-19 on buffy
on a PC running MS Windows ME, but it was there also when I used GNU Emacs
20.7 and MS Windows 95. I do *NOT* have the problem with
GNU Emacs 20.7.4 (alphaev56-dec-osf4.0d, X toolkit) of Wed Feb 28 2001 on
gram
under suse linux, so I suppose it is i bug in the MS Windows specific code.
Best regards, Lars Hansen <larsh@math.ku.dk>

Please post a minimal file that can be used to recreate this problem.
Thanks.

I se the problem in any file (with enough lines) e.g. abbrev.el from the
Emacs 21.2 package. But this morning I found out that the problem disappers
when I don't use any .emacs file. My .emacs file is very large, so I will
try to
make a minial one with which the problem is there. But that will take a
couple
of days...

same here, my .emacs.el is also very large and some add-on package is
causing that recentering. Do you by any chance use mic-paren.el?
That could be the culprit. But then again I've been living with the
recenter 'feature' for more than 15 years now and though it still bothers
me every once in a while I'be learned to ignore it.

Does this problem happen reliably, or is it random?
Can you tell us a way to reproduce it?

I do not use mic-paren.el. I think the features of that module is included
in paren.el
of Emacs 21.
