Hi Coley, could this problem be due to low memory on your computer, or too many applications running at once? I recently cleared many of my non-art files or moved them to an external hard disk, and that helped significantly.
Personally, I have observed over the years that my Photoshop tends to crash sometimes when clicking and dragging the eye dropper tool, so now I only use that tool in a very particular way (without dragging). Also, I “command + S” on my Mac like a crazy person every 10 minutes while painting, almost automatically these days. Hope you’re saving regularly, too!
