Thanks for the comments. My machine makes the spool stand up. Also, I noticed that is not snapping when I am well into the piece of fabric. It's just when it starts. Sometimes I like to chain piece, and it happens just when the next section of fabric is about to go under the needle. I have tried advancing the fabric by hand turning the wheel, and even setting the machine on its slowest speed. That works for a little while, and then it happens again.
True4uca I wonder if I should just use the rest of this spool as bobbin only, and open a new spool.
