[request] App.focus() should work with fullscreen apps too

[RaiMan]

*** workaround ***

simulate the system's app switching keyboard and/or mouse actions
e.g. on Windows alt-tab

----------------------------------

I'm using a full screen GUI along with a simulator application. I open the simulator successfully, then I manipulate the GUI. Later in the script when I need to access the simulator, it's hidden behind the GUI so .focus() does not work.

With simApp = App("BodyTom Simulator") declared at the top I've attempted:
1. simApp.focus()
2. if not simApp.window():
        openApp(simApp)
        simApp.focus()
    else:
       simApp.focus()

P.S. I am running on Windows.

Any help would be greatly appreciated!

Thanks!
