21.2 interacts badly with WM

------------------------------------------------test with 20.4 step 1a: % xemacs-20.4 -vanilla & i get one frame step 2a: restart my wm (it is gwm: it undecorates all windows, then reloads init files, finally decorates all windows) step 3a: i have one xemacs frame, the original frame ------------------------------------------------test with 21.2b1 step 1b: % xemacs-21.2b1 -vanilla & i get one frame step 2b: as step 2a above step 3b: i have one xemacs frame, the original frame, AND a second, void frame, taking the whole of my display. when i iconify this larger frame, all of my xemacs frames are iconified, when i kill it, my xemacs dies here i put windows' descriptions for my mail frame and the spurious one Window: Emacs.emacs.emacs:_mail_to_?＠boffi95: Geometry=593x626+180+70 Window: Emacs.xemacs-21_2-b1.xemacs-21_2-b1＠boffi95: Geometry=1002x770+0+0 note that my screen is 1000x750, probably the extra space is courtesy of gwm session management? 21.2 has session management, i cannot remember about 20.4...
