….put a check in the Double-click a window's title bar to [zoom or minimize] checkbox.
I took a peek and that’s how my Dock was set up….perhaps a default setting as I’ve never goofed with the Dock preferences. Although that didn’t work for me, freelance’s method did the trick.

All’s well that ends well.
