When you copy and paste, Photoshop has, for many versions, behaved the same way. It puts the pasted material in a new layer. Getting rid of the white background should be easy. You can Select -> Color range... or use the magic wand. You'll probably want to anti-alias the edges. When the white is selected, just hit the Delete key. White gone. You can also Ed9t -> Transform and scale, rotate or move the new layer.
Thanks, RMM, but so far I'm not having the problems discussed when I open the two files I wish to cut from and paste to simultaneously as discussed in my most recent comment. As you can see in the illustration the rectangular white background is no longer there.
