Nymea:app return to default window

if I am working on a magic (or other sub window) when I click on a different application (say a terminal window), Nymea:app automatically closes the window I was on and returns to the default (i.e. group main window). Is this a nymea default and how do I change it so it remains on the window I was working in?

Did you perhaps check the “Return to home on idle” option in “App settings -> look and feel” ?

apparently I checked that at some point. Thanks.
sorry for bothering you.
