In GNU Emacs 21.2.1 (i386-msvc-nt5.1.2600) of 2002-03-19 on buffy configured using `configure --with-msvc (12.00)' Important settings: value of $LC_ALL: nil value of $LC_COLLATE: nil value of $LC_CTYPE: nil value of $LC_MESSAGES: nil value of $LC_MONETARY: nil value of $LC_NUMERIC: nil value of $LC_TIME: nil value of $LANG: ENU locale-coding-system: iso-latin-1 default-enable-multibyte-characters: nil Please describe exactly what actions triggered the bug and the precise symptoms of the bug: ;; eg (require 'mouse-drag) (define-key global-map [M-down-mouse-1] 'mouse-drag-drag) (setq automatic-hscrolling t) ;; switch to an interesting buffer (setq truncate-lines t) ;; 1. put point in the middle of a line ;; 2. do a leftward M-drag ;; 3. Notice that as the cursor approaches the left edge of the ;; screen, the hscroll resets to 0 A quick fix is to modify the (let (...) ) in mouse-drag-safe-scroll to temporarily unset automatic-hscrolling. I don't know whether that's a real fix or just a workaround -- I don't understand this comment in scroll-right: If `automatic-hscrolling' is non-nil, the argument ARG modifies a lower bound for automatic scrolling, i.e. automatic scrolling will not scroll a window to a column less than the value returned by this function. p
