[BIGBOX] Windows Media PC, some store fronted PC games not garnering focus on launch

[loggin]

So I'm using Bigbox on my media PC to launch games as I primarily use a remote and game controllers on this system, I've been having some issues launching some Steam games where I suspect an interim steam loader process is starting and exiting and then shifting the focus back to Bigbox leaving the game starting up in the background, I've disabled start up screens already, even had a play disabling focus on exit but so far no luck in getting a clean transition.

I've also noticed this is happening with some EA games too.
