Several times NTemacs 21.3
GNU Emacs 21.3.1 (i386-msvc-nt5.1.2600) of 2003-03-27 on buffy
has written in an adjacent window instead of its own. YAP most often
(the dvi displayer part of MikTeX), although I think that is incidental.
My best guess is that it happens when the XP Windows Task manager says
emacs is about 40MB and when I have more than 256 open buffers
(240 regular buffers and another 32 hidden buffers (with " " as the
first character of the buffer name).
C-l brings the emacs display back to normal. Then a few commands later
(probably page up or page down) emacs writes in the wrong window again.
As near as I can tell, the contents of the emacs buffers are not damaged.
I kill emacs and restart emacs. Then everything is normal again.
I am running Windows XP Home Edition Version 2002 Service Pack 1 with a whole
.bunch of weekly MS updates.
I sense two problems, one is that some variable in the C code for emacs is
overflowing. The other is that Windows is allowing the erroneous emacs
internal screen writing call to write in a screen area that should be blocked.
Has anyone else seen this behavior?
Can one of the maintainers figure out what is happening?
Thanks
Rich
