[Bug] XEmacs-21.0-b47/pre4; Popup menu at buttom/right

Didn't see anything related in the pre5 announcement... My popup menu appears at the buttom/right of my screen (window manager ctwm-3.5). '--with-session=no' worked for XEmacs-20.3 (wasn't necessary in XEmacs-20.4), but does not help now. - Christoph uname -a: SunOS skrjabin 5.6 Generic_105181-04 sun4u sparc SUNW,Ultra-1 ./configure '--with-gcc' '--prefix=/home/clstaff/wedler/xemacs/xemacs-21.0-in' '--package-path=/home/clstaff/wedler/xemacs/xemacs-packages' '--with-tooltalk' '--x-includes=/usr/local/include' '--x-libraries=/usr/local/lib' 'sparc-sun-solaris2.6' '--dynamic' '--with-xface' '--cflags=-O2' '--with-session=no' XEmacs 21.0 "Uzbek Black" configured for `sparc-sun-solaris2.6'.
