Ok... I'm an old guy trying to figure out this Dinc thing.  I don't think I'm an idiot.  But HOW DO YOU CLOSE AN APP????

I have AppKiller which can kill off an app, but when I open the Internet window, I can't find a Quit option in the menu.  I thought that was insane, then I noticed none of my apps have a quit.  This can't be right so I must have missed something in the 300+ pages of my manual?
