Economic Science eats my process output

Dear Bug Team! I live in XEmacs and execute many shell commands with the backgroud package. Unfortunately, on upgrading to XEmacs 21.4.7 this package no longer works for me. xemacs-21.4.6 -vanilla -eval '(background "ls" )' gives me a listing of the current directory in the "*background-1*" buffer. xemacs-21.4.7 -vanilla -eval '(background "ls" )' gives me: --- working directory: /home/burt/ % ls Done 12:53:51 Where has the output of the 'ls' command gone? Curiously, if I type '(background "sh")', and then 'input' 'ls' at the shell prompt, then I do see the directory contents. The two Emacs' were configured with the same options. Has anything changed in the process handling code between versions? --- Alastair ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux mastiff 2.4.4 #1 Wed May 16 01:26:02 GMT 2001 i686 unknown ./configure '--site-includes=/home/burt/lib/compface/include' '--site-libraries=/home/burt/lib/compface/lib' '--with-mule=yes' '--with-xpm' '--error-checking=none' '--prefix=/home/burt/lib/xemacs' XEmacs 21.4.7 "Economic Science" configured for `i686-pc-linux'.
