Hi, my free version of the 2D program often crashes and closes without a previous warning since much time on Windows 10, I am stressed for that all the time because it is quite annoying to click on manual save each 5 minutes for not loosing all the previous activity. Could any other type of program cause the issue by interference eventually? And automatic save never works regularly, I cannot rely in any time on this. The computer was always clean and save, of course. Thank you for your help.
