Cannot close window when click red X button
Sometimes I click red "X" button or yellow "-" minimize button on the top-left corner of window, the window cannot be closed, it likes you don't click, but the animation of the button tell us you clicked really and truly and click-event is received by it . If you move the window, then it can be closed.
It happens on any windows of any applications you opened,chrome, system apps etc., especially easily re-produce after hours of idle of app.
This problem was reported even about 10 years ago in Apple discussion,
see Re: Cannot close windows by mouse-click on red button, and Cannot Close Safari window Using the Red Button
But now it still annoys us.
What has been doing Apple?
