@th3j35t3r @MisterE several options on Linux, nudge, nudge, free yourself, but also LibreOffice Draw is available for Windows and I think MacOS, and it can edit them. I like Xournal++, which oh hey IS available for Windows. Surprised.

Good luck!

Thanks. I'll see what works. Nudge, I'm staying away from Linux as I had enough nonsense getting Linux to run on my mainframe.
