In this case, it looks like calling code (Hrvoje's dframe-xemacs-popup-kludge) has already been hacked for XEmacs, so I propose the following change diff -u c:\Program Files\XEmacs\xemacs-packages\lisp\speedbar\dframe.el.~1~ c:\Program Files\XEmacs\xemacs-packages\lisp\speedbar\dframe.el --- c:\Program Files\XEmacs\xemacs-packages\lisp\speedbar\dframe.el.~1~ 2002-11-18 05:56:11.000000000 -0500 +++ c:\Program Files\XEmacs\xemacs-packages\lisp\speedbar\dframe.el 2002-11-18 05:56:11.000000000 -0500 ＠＠ -818,7 +818,7 ＠＠ (beginning-of-line) (forward-char (min 5 (- (save-excursion (end-of-line) (point)) (save-excursion (beginning-of-line) (point))))) - (popup-mode-menu) + (popup-mode-menu event) ;; Wait for menu to bail out. `popup-mode-menu' (and other popup ;; menu functions) return immediately.

In Emacs `mouse-position' returns positional values based on standard character cells, even if the cursor isn't over a character. Additionally, Emacs returns (FRAME X . Y), XEmacs returns (WINDOW X . Y). See: http://list-archive.xemacs.org/xemacs-beta/200207/msg00225.html Lots of code is written to Emacs spec, including code shipped with XEmacs. Rather than fix all that code (and future code), it might be more straightforward to change XEmacs' `mouse-position' to follow Emacs spec, at least by default. -- John Paul Wallington
