Native apps on Apple OS display a spinning beachball when they lose control of themselves.

The 'Force Quit' panel is how to know the app is unrecoverable and needs to be killed or force quited or relaunched.

I just experienced a lengthy delay and the lower half article display was missing in blank completely.

(dotimes (i 100000000))nil

No hourglass appears. The summary article panel, at upper half, follows the mouse pointer with highlight between square brackets before nil appears, it seems.
