There is an attachment available for many machines that minimizes this - and at the moment I am unable to think of what it is called.
My machine is a Janome, fairly new at 10 years, but I have noticed this quirk since the beginning. I read somewhere that this is a problem with most machines and it's just something we have to learn to live with. Only way to get around it would be to use the big clunky quilting foot which really isn't a good option. I'm going to see if I can find more about the attachment you are referring to.
