I'm afraid that doesn't fix it for me. I've been watching the list this week because the problem had already been reported (twice) before Ed. The main symptom is that XEmacs stops updating text. Background colour seems to persist, but wherever there's text there's no updating going on at all (for example, if I minimise and restore then I get the wallpaper apparently showing through in stripes where there would be text. Without subprocesses, this is a pretty crippled version! Unfortunately the net installer that's used for Windoze installs doesn't give me the option of regressing to a working version. This behaviour is new to this release. Previous releases (many) have been fine. However, I confess that I updated both Cygwin and XEmacs at the same time so I don't know which update caused the breakage. I have a very similar setup to Ed but with a more recent Cygwin: source$ uname -a CYGWIN_NT-5.1 vogue 1.5.4(0.94/3/2) 2003-09-12 23:08 i686 unknown unknown Cygwin ^^^^^ XEmacs 21.4 (patch 13) "Rational FORTRAN" [Lucid] (i686-pc-cygwin) of Sun May 25 2003 on TSUNAMI
