Nope, no other windows open. I’m an IT guy for a living, so we can skip the usual user misunderstandings 
. I also don’t have this issue with any other app/game. Like I said, not a big issue by any means. Just sometimes I’ll click to select landing challenge or to start a flight then turn around to take a quick sip of my drink or whatever then turn around to see I have to click again. Minor nuisance.
