I think I have got all the ones I can reproduce. I am hoping that means all of them. Thanks to Damon and Stef for reproducible test cases. Bizarrely their problems were unconnected although the symptom was the same. I also fixed a bug which may have been the cause of the endless redisplay bug that some are still experiencing. I will apply this to cvs. andy 1999-09-22 Andy Piper <andy(a)xemacs.org&gt; * gutter-items.el (update-tab-in-gutter): use last-nonminibuf-window instead of selected-window. 1999-09-22 Andy Piper <andy(a)xemacs.org&gt; * redisplay.c (redisplay_frame): reset the gutter display lines when we reset the subwindows. * gutter.c (reset_gutter_display_lines): new function. * window.c (Flast_nonminibuf_window): new function equivalent to FRAME_LAST_NONMINIBUF_WINDOW (). (syms_of_window): declare it. * redisplay.c (create_string_text_block): don't add bogus eol markers to gutter display lines. * glyphs.c (reset_subwindow_cachels): make sure we unmap subwindows using unmap_subwindow so that expose events get registered correctly. * window.c (window_scroll): use Vwindow_pixel_scroll_increment to determine how much to scroll the window. (vars_of_window): Vwindow_pixel_scroll_increment is a new variable. 1999-09-21 Andy Piper <andy(a)xemacs.org&gt; * lwlib-Xm.c (xm_update_label): don't clobber pixmap type labels with text. -------------------------------------------------------------- Dr Andy Piper Senior Consultant Architect, BEA Systems Ltd
