Force mouse focus to game window

@anonymous_user_9c39f750 Britain - thanks for the try, but I don’t know how I would incorporate C++ into something Blueprint based. I am sure there must be a way (and I appreciate the help) but there must be a check-box somewhere that I can click that just handles this issue for a Blueprint project? Anyone know where this checkbox is, or other magic fix?

Is it some sort of argument / option when opening a level to retain focus?
