Enclosed are screen shots. temp1.jpg shows the notation window, just before I press the green lead sheet button shown with the red arrow. temp2.jpg shows what happens after I hit that button: it switches, not to lead sheet, but to chord window. If i then hit the green lead sheet button there, shown with the red arrow, nothing at all happens.
