bottom of card off screen, but bottom < item 4 of screenloc

[Dr. Hawkins]

I'm scratching my head here.  Am I missing something obvious (again), or is
something off kilter here?

The bottom of a stack is off the screen. Yet "the bottom of stack out4"
yields 1111 (which should be on screen; this is a 27" iMac!), while the
"working screenRect" is 0,22,2560,1436 (which appears correct).

(this is from code trying to keep new stacks on screen)
