@Sig, you can see running processes by opening up your activity monitor. But activity monitor won't give you a sense of the parent/child relationship among processes. To see these, open up terminal and type "ps -ef." You can pipe this command to the "more" filter, which will page it on the screen. But if you want a quick and easy way to locate a process, just grep the application or utilities name:
>ps -ef|grep TextEdit
this will return a line that includes essential process info and give a clue if the process is running under a parent or is rougue.*
If you're unfamiliar with UNIX shell commands, I suggest you read up before typing up stuff in terminal. If you're a UNIX maven, apologies.
*Actually, this will return two lines (at least) that contain "TextEdit." One will be the running process, the other will be the process in which executes the grep.
