I downloaded it by the numbers, but it was the same iteration I already had. (It says something about "frozen for Classic" at the site.) I do have a fair number of shared files, but not really that many. Here's the kicker: when I first upgraded to Pro 4.0.2, I experienced an incredible increase in speed. I was amazed by it. That lasted for at least three months. My point being, with the system I have Pro once worked blindingly fast, then for some reason three months later slowed to an almost imperceptible crawl where it has remained.
