I have a serious problem with 21.4.9. Each time I do su to edit a file as root using xemacs, when I select text it hangs forever. This doesn't seem to happen if I am not root. Killing xemacs gives this: Lisp backtrace follows: own-selection-internal(CLIPBOARD "BuildRequires: tcp_wrappers-devel, pam-devel, db3-devel, libldap2-devel, openssl, openssl-devel, XFree86-devel" nil nil) # bind (zmacs-region-stays data-type how-to-add type data) own-selection("BuildRequires: tcp_wrappers-devel, pam-devel, db3-devel, libldap2-devel, openssl, openssl-devel, XFree86-devel" CLIPBOARD) # bind (push string) own-clipboard("BuildRequires: tcp_wrappers-devel, pam-devel, db3-devel, libldap2-devel, openssl, openssl-devel, XFree86-devel" t) # bind (replace string) kill-new("BuildRequires: tcp_wrappers-devel, pam-devel, db3-devel, libldap2-devel, openssl, openssl-devel, XFree86-devel") # bind (undo-high-threshold tail verbose end start) kill-region(947 1057) # bind (entire-line arg) kill-line-1(nil nil) # bind (arg) kill-line(nil) # bind (command-debug-status) call-interactively(kill-line) # (condition-case ... . error) # (catch top-level ...) uname -a: Linux rpppc1.md.hns.com 2.4.18-5 #1 Mon Jun 10 15:37:14 EDT 2002 i686 unknown ./configure 'athlon-redhat-linux' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--datadir=/usr/share' '--libdir=/usr/lib' '--mandir=/usr/share/man/man1' '--infodir=/usr/share/info' '--with-pop' '--mail-locking=lockf' '--with-clash-detection' '--debug=no' '--error-checking=none' '--with-mule=yes' '--with-database=berkdb' '--with-ldap=yes' '--with-canna=yes' '--with-wnn=yes' '--with-xim=xlib' '--with-msw=no' '--with-xfs=yes' '--with-dragndrop' '--pdump' XEmacs 21.4.9 "Informed Management (RC2)" configured for `i686-redhat-linux'.
