This is not working because the kill command does not accept the name of a program. You have to give it a process id. As for your general question, we really can't answer it. There a lot of reasons a process might not die when you try to kill it: it could be trapping and ignoring signals (which is rude but it happens), it could be stuck in a critical section, the program might be threaded and not handling signals well, the program might have forked itself and the original process id has disappeared, etc. We can't read your mind or divine what's running on your computer, so we can't answer your question. We can only suggest things that might be wrong. It's up to you to investigate and/or dig deeper. Carl Banks -- http://mail.python.org/mailman/listinfo/python-list
