I can't believe this one isn't fixed yet -- this bug has existed since at least 19.12. If an xemacs subprocess (for example, something running in a shell buffer) produces output as quickly as possible, you cannot interrupt it. You either have to wait for it to complete, or kill the job from another terminal. To reproduce: xemacs -q M-x shell Do something that produces a lot of lines very quickly, for example: od /boot/vmlinuz Watch it scroll by for a few seconds. Now you want to stop it by typing C-c C-c... Type C-c XEmacs is now completely hung. Type the second C-c. No effect. Go to another window and do "killall od". XEmacs immediately comes back to life. Seen on at least: XEmacs 21.4.8, 21.1.14; Red Hat 6.2, 7.0, 7.2, 7.3, 8.0. -- Jamie Zawinski jwz(a)jwz.org http://www.jwz.org/ jwz(a)dnalounge.com http://www.dnalounge.com/
