Every few hours Painter crashes so that the cursor turns from the brush icon to the regular arrow and if I click in the Painter area, it freezes. Other programs work fine. I have not yet found a pattern with these crashes, however, it is not due to overheating. I normally use Painter on 300 ppi files of up to 20 cm x 30 cm. I do use many layers but the crashes seem to happen regardless of their number. I have reinstalled and reset Painter once already when it crashed and would not start up again, but it doesn't help with the regular crashing. I've had Painter on the computer for 2 months and it's been doing this all that time.
I am really at a loss here, if anyone has suggestions on how to proceed and try to work out where the problem is, I would be very, very grateful!
