There shouldn't really be any behavior changes related to that in any of the recent updates. When you say pressing the left arrow, do you mean the arrow at the top left of the window in the title bar? If I press that arrow, I definitely don't see the prompt asking if I want to exit.

Hallo Mike,

Yes, I meant the arrow at the top left of the window. I now checked it again and it works fine now! 
I have unfortunately no clue what caused this behavior and why it went away.

Thank you anyway for your response!
