... we've been replacing my work PC, which accelerated its previously-slow decline yesterday, and decided to end it all quickly.
So instead of a 2005 XP system with 1.2GB of RAM, now I have a 2013 Windows 7 with 4GB. Much better.
So we got all the data & programs transferred, and everything's working ... except the driver for my all-in-one printer/fax/scanner/copier was for XP/Vista. Working on getting the up-to-date driver now, and then it will all be better.
