Don't see the dashed rectangle enclosing a pasted image
When I pasted an image formed using the polygonal lasso tool into another Photoshop document, I could modify the shape (extend or rotate the image) by manipulating the dashed rectangle formed round the pasted image.
This rectangle was most useful to work on the right form of the pasted image.
But I notice that tTHE SUPPORTING DASHED RECTANGLE IS NO LONGER AVAILABLE.
WHY IS THAT? AND ONE HAS TO PASTE A PROPER SIZED IMAGE which is not easy at all.
PLEASE EXPLAIN WHY THIS HELPFUL FACILITY HAS BEE WITHDRAWN.
