I tried to kill it using the PID and kill command. And it said "operation not permitted". I tried to su into root to try it and I could not su - even though I typed the root pw exactly it wouldn't let me. I know in FreeBSD you have to a member of the "wheel" group but I don't support Xubuntu is like this.... Why couldn't I su? I tried sudo in front of the kill command but that wasn't right syntax or something... How can I be insured to be able to kill a process? I'm not going to whine about 8.10, FF3 ect.... </blockquote><div> Michael has responded to the request to kill the process, and hopefully that will help you. To access a root account in xubuntu, try the command "sudo su" from the terminal.  It will prompt you for your user password just like sudo normally does, and then will bring you into the root account. Of course, all necessary warnings to "be careful" apply here.  :) Jim </div></div>
