I have a tangentially-related question. I've been using Novagraph Chartist since the Windows 3.1 days back when I was 17 (I'm now climbing 50!). It seems that the original company behind this has vanished, I've asked for support, but no joy there, I hope the author is still alive. I'm on Chartist 5.2. It needed online activation towards the end of its life.

Whilst in these modern days of hi-DPI screens and anti-aliased lines, I still love using Chartist - I know all of the keyboard shortcuts and I can use it to create a diagram faster than using anything else.

Does someone have a patch for it or something?

Thanks, Nick.
