Hi Gang: I found a problem with Viper in emacs-app. This is a different bug than the one that exists in NS-9.0rc3. But, it has an easy solution. Place the following in your .emacs or something: (require 'levents) (defun viper-cond-compile-for-xemacs-or-emacs (xemacs emacs) (if (featurep 'xemacs) xemacs emacs)) Rodney
