What version of Hypercard does this?  I'm using 1.2.5 and receive no dialog for
"New Background".  I know of a dialog and check box to copy current background
when "New Stack..." is selected. 

My solution is:

	1. Create a new stack and check "Copy current background".  This also
	   copies the stack and background scripts (and executes any 
	   "openStack", "openBackground"  and "openCard" handlers).

	2. Make your changes to the background in the new stack.

	3. Copy the card and paste into the old stack.  Since the new
	   background now differs from the old background, a new ID is created.
	   (If no changes are made to the new background, it merely becomes
	   another card in the old background.)

It works, but involves extra steps over a simple "New Background" dialog.
Changes to old and new backgrounds later will not be reflected in the
counterpart.

(I hope this article isn't being seen twice.  I may have screwed up in sending
it the first time.)
