emacs, cygwin, and revert-buffer

[Swenson, Eric]

Hello,

I've searched the web with google and can't find any discussion of a problem
I'm having with emacs running under cygwin (on Windows) in a window (I
assume this means that this is xemacs rather than emacs).  Perhaps someone
on this list could help, or point me in the right direction (or where I
should go for help).  

The problem is that frequently revert-buffer corrupts the buffer when the
on-disk version of a file has changed.  I've verified that when running
gnu-emacs not under cygwin Xfree86, the buffer corruption doesn't occur.  I
can't quite put my finger on the nature of the corruption, and the simple
cases I've tried to conjur up work fine.  However, with large source files
or text log files, where I invoke revert-buffer when the cursor is sitting
in the middle of the buffer (i.e. not at the end), the resulting buffer is
corrupted near where the cursor is.  It is corrupted in that a portion of
the file appears duplicated (perhaps by the difference in length of the
original buffer and the modified file).  

My emacs version shows:  GNU Emacs 21.2.1 (i686-pc-cygwin, X toolkit) of
2003-11-23 on DRACO

I'm running XFree86 version:  4.3.0-1

I'm running cygwin version:  1.5.3-1

I got this version of emacs from the above version cygwin distribution.  

Has anyone seen a problem with revert-buffer similar to that described
above?  Any suggestions as to where I could go for help?  

Thanks much.
