XBox Controller does not talk with out-of-Focus Window

Hi All,

my XBox game controller (wireless), installed in Windows 10, worked perfectly for a few days.

Now it happens that if a window goes out-of-focus (because for instance another window has been clicked on) the game controller does not communicate any more with that window, as long as it stays out of focus. Clicking on it, the communication is back active.

I think the default behavior is that the controller keeps communicating with with all windows, focussed and un-focussed, even minimized.

But I am not able to find the setting that controls this behavior.

Can anybody help on this?

I do thank you all very much!

:)
