Dear Ken,
Thank you so much for your reply. I've done everything you suggessted, a few times...but it's still doing the exact same thing... :(
I've even tightened and loosened the bobbin tension, but it makes absolutely no difference...
Another thing that I didn't mention, is that it will sew a few stitches and then the machine will stop sewing because the threads got all tangled up at the bottom, big ugly bird's nest!
I've officially gone into stress mode now...
