I started to try the strace suggestion, and to simplify things, I logged in as root, rather than user followed by su - . To my surprise, the problem disappeared. Therefore, to demonstrate the problem: 1. log in as user (not root) 2. (in my case) startx 3. pop a Shell Konsole 4 su - 5. tail -f /var/log/<some log file you can send to> 6. click the x to kill the Konsole 7. pop another Shell Konsole 8. su - 9. ps -ef | grep tail 10. I find that the tail process persists But not if the original login is root. I wonder if anyone else can reproduce this. I hear from above that it is now bedtime at -0500, so I'll try the strace tomorrow. Thanks for your interest. Mike.
