The samples are the files supplied in the Samples folder. I was just trying to look through them and try them out, as I imagine most people do, that's what they're there for, right? The ones I've just checked are not Read-only files. I haven't set any options, the program is as supplied, a fresh download when my registration was confirmed last night.
However, I am still getting the "cannot save file" message even after closing the program down and re-opening it - the message pops up when I try to run a code file by clicking the "play" icon. Once dismissed the code runs. I shall go through it again and document it exactly.
I have been playing with unregistered BASIC4PPC on my Win XP laptop for a few days without encountering this phenomenon - the new download is on a Vista desktop.
