Jan, sorry for interrupting the work on your thesis. Vin, we need to fix this for 21.1.9 xemacs-21.1.9pre -geometry +200+100 -vanilla click button3 and get a menu at the wrong position. for 21.1.7 the following patch was applied: 1999-08-28 Jan Vroonhof <vroonhof(a)math.ethz.ch&gt; * menubar-x.c (make_dummy_xbutton_event): Don't add offset twice if HAVE_WMCOMMAND is defined. http://www.xemacs.org/list-archives/xemacs-patches/199908/msg00080.html I don't pretend to understand this, but HAVE_WMCOMMAND is definitely a 21.2'ism. I can fix the problem by removing the whole #ifdef HAVE_WMCOMMAND block from 21.1.8 (of course we could then eliminate shel[xy] altogether). suggestions? Gunnar BTW: I still can't build 21.1.9pre on Irix5.3 with gcc... :-(
