Since updating the Wacom Driver and Software from 6.3.36-1 to 6.3.38-2 Corel Painter 2020 (updated Nov 2019 version) has crashed completely twice returning the screen to Desktop. This was after a period of over 1 hour and sadly I lost the work I hadn't saved recently.
Uninstalling the Wacom Driver software and reinstalling the previous seems to have fixed the problem. The New Wacom Software had a new UI and looked promising, but new and shiny isn't much use if it's unstable is it.
BTW there doesn't appear to be a facility in Corel Painter to automatically save work periodically if the user so chooses. This is available in Photoshop and many other programs and would surely be a simple and useful feature addition?
Sorry for amibiguity, in both cases the crash occurred after more than an hour of working with Painter 2020. On one occasion it was when using hand gestures on the Wacom Pad (Intuos Pro Medium post 2017 model). On the other I simply stroked the stylus on the Wacom Pad and it all disappeared from the screen.
Dan, whenever a crash occurs, I go straight to Documents > Painter 2020 Recovered Files to find my latest work, sometimes two, carefully waiting for me to carry one. It's a regular feature with Painter 2019, 2018, 2017 etc
Thanks for the information Nikolay, I'll make a note so that I remember. That's very helpful.
