Hi, whenenver I open a haskell file (*.hs) with my xemacs I get an annoying warning in a splitted window: (1) (error/warning) Error in `post-command-hook' (setting hook to nil): (void-variable imenu--index-alist) The modes (Haskell Font Ind Doc) seem to work, though. My xemacs has [version 21.4; April 2001]. I use this xemacs as it was installed without any customizations under Suse Linux 2.4.19-4GB on i686. I've found write-protected /usr/share/xemacs/xemacs-packages/lisp/haskell-*.elc files. The haskell-mode.elc does not seem to be the latest version: (defconst haskell-version "1.43" (#$ . 632)) I don't know how to include the *.el files of the latest haskell mode in xemacs. (I've no problems with GNU emacs.) The problem occurs on several laptops. Does someone has an advice? Thanks Christian
