When zoomed in, can't move image with hand

Also, when I resize a window, the image resizes. I just want the window to change size, not the image. I see "zoom resizes window and have that - unchecked.

Usually (pre-Intel) I could have image zoomed and hand drag around anywhere - and beyond picture bounds.

That is the kind of thing that I would expect when PS is RAM starved. Check your available RAM and PS RAM allocation. The MacIntel boxes want more RAM for Rosetta and probably for general operating overhead as well.
