In previous versions of LR, if you selected several stacks of photos and used the shortcut "S" it would toggle all the images in all the selected stacks to expand/collapse. Now it will only expand/collapse the first stack of photos. Please fix this ... I use that a LOT!
Thanks for the reply. Very odd. It was behaving this way yesterday every time I tried. Today it's expanding/collapsing as expected. Not sure if it is intermittent and/or in combination with something else. I'll keep my eye out and see if it happens again. If so, might have a better clue as to conditions causing the behavior.
