Thanks, 3D! Years ago I used a paint program (Colorix) that did't even have one level of undo, so I got used to saving a lot, so that part doesn't do a lot for me (I don't make mistakes (Ha!)), but it does come in handy for my students. The earliest version of Photoshop I can remember using was 2 (on a Mac), and I would say up to version 4 each one had worthwile improvements. I can no longer wrap my mind around how Photoshop want to do printer ink cailbrations, for example, and I still don't understand why the gamma factor on PCs seems to default to the Mac Gamma factor (but at least now they tell you that). Incidently, version 5 (and 5.5) installed on the school's Gateaway computers with the monitor profile so incorrect they were unuseable (I think maybe Gateway's fault), PS should default to RGB correction off, not on, to cover cases like this, as many users don't know where to adjust this or turn it off.
