The hang is from 10 to 20 seconds. Greatly slows things down. This is disappointing because Painter 2019 was advertised as much faster than P 2018. I am going back to using P 2018 until this is resolved as it is making P 2019 almost unusable. Running on late 2013 Mac Pro, Mojave 10.14.1. Please resolve asap, thanks.
Sorry I didn't respond 4 months ago - got distracted with other things...
John, thank you for sharing Stephen's tip and your own experience. Honestly, you both are the guys who gave me my Painter back now. Due to the freeze issue, the software was useless for me for some time. I'm glad having it back again. Best regards + happy painting! Alexander
Thank you, Stephen! This gave me back my Painter. Great!
