Uncle Bob and justjimmy, I had the same result for quite a long time. But I then got it to work--by focusing only on her outside foot. (Scroll down so that only that portion of the image is visible if you have to--that definitely helped for me.) When that foot is going from left to right, and you think it's supposed to be her right foot swinging toward you, try to picture it as her left foot swinging away from you--and conversely, when it's going from right to left, try to picture it as her left foot swinging toward you instead of her right foot swinging away. If/when you get to the point where you see the foot swinging in the other direction, scroll back up, and the body will be going with it.
Good luck!
p.s. This reminds me of an argument I got in with my clueless first grade teacher when I was six. She had drawings up on her wall of two hands--one on the left side of the blackboard with the thumb pointing to the right, and on the right side of the blackboard with the thumb pointing to the left. Both drawings were just silhouettes. At one point during class, when she was teaching opposites, she asked me which drawing was the left hand. I pointed to the one on the right side of the room. She told me I was wrong. I raised my hand again, and when called on, I insisted (probably too vehemently) that I was correct--the one on that side of the right side of the room was the left hand. She got upset at me and sent me to the principal's office. When the principal asked me why I was there, I told her what had happened, and that I was 100% certain that the teacher had the drawings wrong. A few minutes later, when recess started, the principal and I went down to my classroom--with the principal clearly expecting my teacher to quickly prove me wrong. After my teacher continued to insist I was wrong, I walked up to the drawing on the right side of the room, and held my left hand up to it--palm facing outward, with the thumb pointing left--and declared in a very upset voice, "SEE?!? I WAS RIGHT!!! IT'S A LEFT HAND!!!" The principal burst out laughing, and my teacher got red in the face and muttered something under her breath. I was released to go out to recess. When the class got back in, both drawings had been updated to include knuckles and fingernails, to make it clear that they were the BACKS of the hands.
