Thanks all. I did notice through settings/applications that several things seemed to be running, and that's why I asked. And I say "seemed" because I'm not entirely sure - I'm used to windows task manager.
Also, thanks for making me feel not-so-old.

I think my earliest computer memory is checking out a book from my elementary school library and attempting to make a neighbor's commodore 64 do... something. Danger if I can remember what, though. My brain's not made for programming, though. I get way too frustrated way too easily... and distracted... got a little of that ADD-oh look, a squirrel!
