Icons in Finder window won't let me move them

I am trying to sort and arrange some icons in my finder window. I used to be able to arrange them by name (or kind, or whatever) and then move them around at will. Now, if I arrange them, they keep bouncing back to where they were when I try to drag them somewhere else; and if I indicate that I want them arranged by None, suddenly they sprawl all over the place, on top each other, spread out wider than the window...

I found a post about a problem something like this on the discussion boards, and the reply was a smug, "Well, you'll just have to do things differently." I don't want to do things differently, I want to be able to arrange my icons by name, drag them where I want them while I sort them and put them in folders, and then arrange them again when I'm ready. That's how it worked on all my previous Macs. So how do I get it to work that way now that I've got Sierra?

While we're at it, when I have it arrange the icons by Kind, it shows only a tiny sample of them and I have to go clicking to get it to show more. How do I make it arrange the icons by Kind and show all of them at once, the way it used to?
