Agreed. Since sharing input between multiple applications (and the OS services) is its primary role, you would think that UI designers would have “thou shalt not steal focus” as a commandment, but that is not the case.

My latest version of the problem is with Ubuntu Gnome. Upgrade software and, later, you will be interrupted with a pop-up window to enter your system password. Not only is this an interruption, I’m always doubtful that this is the system asking for a sudoer password!

UIs, in my experience, are very bad at handling “interrupts”. Sorry, my dad designed chips, so I use that hardware term when talking about notifications and other times another application needs to notify or get the input from user. Personally, I’d have the UI change the color/texture of the system menubar/taskbar and wait for the user to click it.
