I use the quick selection tool A LOT; in the old version I could then click the mask box and fine tune the selection.
NOW -- the box quick selection tool - is o.k. ( I prefer the using the brush selection -- seems to work better) but when I click the mask box -- nothing seems to happen. I'm not a PS professional -- all self taught and of course it's mostly operator error but it's a pain in the butt to have to learn a new trick to master a tool that was I was working pretty well just yesterday. I do tons of photo work for our online stores & wholesale business so I'd like to not have to learn all over again.
