Oh! This happened to me yesterday, and also on my first quilt on Millie. She just stopped, needle down. At the very top of the screen, it said that the program was "unresponsive." So, I had to shut everything down. I have no idea what caused it, but as I am very, very new to this, I did not think about timing. I am just wondering how I pick up my pattern again - I did try, but it was off half an inch. So, I was going to figure out how to use the trace feature, so that I could get it to start much closer to where it stopped.
