animating a bezier circle in 2.5

hi. My animation was going perfectly well, until I started animating the main character. He is a slinky made of a bezier circle. I can move it around and scale it just fine, but I can’t actually animate it. When I make a new keyframe (after the one at the first frame) and scale it, it changes all the keyframes, so instead of animating it it just edits it. Sorry if this is badly explained, but basically I can’t animate a bezier circle.

Thanks in advance!
p.s. I am using blender 2.5


did you try adding hooks to the handles and animating them?

never heard of hooks! Thanks! It might just work… thank you!
