Sometime in the last few days, I've noticed not getting my regular notice to save my work. I checked my Option setting and its correctly checked. I switched to saving a backup copy and that didn't work either. So I switched back and it still doesn't work.
I apologize for the lack of response from the community. I'll try to make time to run a test at home.
Based on my test I have a theory: it doesn't work
<edited: see below>
I guess I need to back pedal a bit. Thinking that I may not have been patient enough or paid strict attention when I tested last night and didn't get any auto saves or prompts. Today I ran a simple test and didn't get any saves but I am getting prompts. I'm running it again to see if I can get saves.
It is saving. So I'm not sure what went wrong before except for user incompetence on my part.
<edit>: Nope, now I saw a backup file once and now it's mysteriously gone. It seems like this function isn't reliable. Perhaps only the prompt function is worthwhile.
Once again a backup file was saved but then it went a way when I did a save on the file. I just don't see how this functionality works or is helpful.
As to what you can do about it IDK. You are just using free 2D and therefore don't have any support from a VAR or Siemens, correct?
Perhaps you can download the version after ST10? It's called simply 2019. I assume it's available for download for free 2D use.
Whether it would work any better is doubtful. No one else is chiming in on this topic unfortunately.
