OK. Using Safari, I got one more step closer ... clicked on the arisaema image on the opening page, I got a page of contents, but to old(er) sets of pages. AND at least one of the ID's offered seems to be from 2001. Do I need to install Navikey v. 4.0 ?? If so, How?? Carolyn Schaffner still in Buffalo, NY, but not yet snowed in.
