Thanks for the offer @MikeyFresh ! It's something to keep in mind for the future. Learning something new would be good for me -- I had to learn how to do the disk image thing at first, too. But I'm still running Moode version 3.x (.8 I think?) and it's working well, so I haven't had a need to upgrade.
btw, I do Mac on a laptop, although my primary computer would be a Windows 10 desktop.
