I recently purchased this used machine and hadn't had time to use it much.

I sat down this afternoon hoping to cruise through some quilt blocks.

Old seamstress habits die hard, I insist on backtacking the beginnings and ends of all my seams and haven't quite mastered the automatic features on this machine and figured my problems (stitching forward and back at odd times) were just user error.

Then, my 3 year old required attention and I ended up leaving my machine on for 2 or 3 hours while I did things with her.

I came back to my sewing, decided to do a plain straight stitch and just press the "knot" button (next to the needle-up/down button) at the beginning and end so I wouldn't have to figure out the pattern of the automatic features.

When I attempted this plan, the machine stitches only in one spot and doesn't just do a quick knot and stop. It continues to stitch in place. I had to turn it off at the switch to make it stop. I tried switching stitches (just to zig zag or the various straight stitches) and always the same result: It just stitches in place-feed dogs are up, but not working. Needle doesn't switch places when I'm in zig-zag mode.

Is this some button I've hit by mistake? I turned it off and on at the switch (because I had to to get it to stop stitching in place.) and disconnected the power cord, and still the same results.

Please tell me it's me and not that I've gotten a lemon!
