That's not standard. If it's a one-window app, such as Skype, it should close the app. BareTorrent is also sort of a daemon process (where you often want it to live in the systray), and it follows standards. Minimize will put it in the system tray and close actually closes it. It's standard and feels intuitive.

I don't think so - I find this very subjective - I've always assumed that X just closes the window, even if it's a single window app. This is consistent, just some applications happen to also run in the background.

That was one of the old differences between Windows and OS X behavior (or app-centric vs window-centric).

If you're reffering to Windows, then X usually closed the app too.

I think his point is the X closes the window, and many, but not all, Windows applications also choose to quit when their (last) window is closed.
