		I changed my batteries after a year on general principal.

	1)  I am very curious as to why several people had immediate battery
	    problems unless it was related to battery shelf life (in the store)
	    where they were old.

	2)  When I changed mine, I had the same problem.  I quick put the other
	    two back in so I could think it through.

	3)  I decided to dump the other two batteries again and, take the
	    calculator firmly in hand, and tap it firmly upside down on a firm 
	    table.  IT WORKS!  I DID NOT LOSE MEMORY!
