About 15 years ago, I remember being aghast at Skype hijacking the X in the top-right, minimizing itself to the taskbar instead of either exiting or minimizing to the system tray. Because there was a clear standard action that was intended by that interaction, and Skype had gone out of its way to override that standard action.

Wait till you find out how Windows has hijacked "Shut down the computer"...

I won't say I'm not annoyed at it. When I want to switch back to the Linux partition and Windows instead decides to spend half an hour installing updates, it becomes another reason not to switch to Windows the next time.

I think GP is talking about how "Shutdown the computer" does not, in fact, shutdown the computer (it puts it in a suspended/hibernated state).

As a fallback, you could always use Alt+Space to open the menu, Ctrl+W to close a window and good ole Alt+F4 to close the app

I've seen alt+f4 not have the desired effect (minimising the app or sending it to the tray instead).

Oh god, I thought I was the only one.
