Hello, I encountered the same thing when writing an internal library used to collect some pre-main-program config from users. I couldn't just make this concurrent with my main window (hidden until required) since it's reusable code. As you've suggested, I just gave the initial config window its own Application. This seems to work fine.
Of course, my main program has multiple windows, and that's OK, as long as we have 1 window we can designate as primary to make it responsible for the Application's lifetime.
