Macybaby, thanks for that information. I have a similar problem with my 130. But then I am always bumping something on it. I store the few extra bobbins I have on the crossbar and hit them regularly. I also knock my pincushion, scissors, seam ripper, etc. off the edge of the cabinet, so I think the problem is mostly with me.
Today I was sewing a patch on a karate kimono. That thing was so thick and unwieldy that objects were flying off all over the place! I was pleased that the machine could handle the project.
