Perhaps you could give some indication. FYI, with the culprit font, (move-to-window-line -1) goes to line 34 (the last line in the window), and recenters the cursor. The move-to-window-line documentation says "-1 meaning the last fully visible display line of the window". So line 34 would be fully visible, so that I don't see why the cursor is recentered. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
