Attached the error!
Do you have some news about?
I too have been experiencing crashing on Sierra. I was running fine and then started crashing the last few days.
Unfortunately I can not click any button!
@Matteo, Cydni: when does this error show? Does it show when you're switching between MoneyWiz and some other window perhaps?
Would it be possible that you e-mail us at email@example.com with a video of this happening?
Of course, I sent you the video!
Thanks, (37 mb!)
