Yes, the information is buried deep within the manual - I just checked and pages 106 & 107 under
preferences will explain about saving backups of your work.
My computer has the habit of closing down and restarting without warning so I have had to get into the habit of saving frequently. I wish we could set an automatic save for every five minutes or so like some of the other software I have used. It's so disappointing when I get the brief message that my computer has to close down and I have forgotten to save and subsequently lose perhaps an hour's work.
I'm glad you have found pleasure in losing yourself in ArtRage and I look forward to when you are ready to show us what you have been doing.
