Quit scrapping already finished paintings!
Seriously! My Sim scraps a FINISHED painting just to start another one... before I can make her sell it! So annoying. And I'm not talking about me taking ages to get her to sell the painting... I mean...

This should be pretty easy for you to stop. Either turn off autonomy or put something else in her queue that makes her walk away from the easel when she finishes painting. I've had lots of painters, including the Sim I've been playing most recently, and I've never seen this happen but I wouldn't allow it to happen more than once or twice. After that, I'd take steps to prevent it.
