Curve follow problem

[Gizmo]

Hi there,
I found a following problem and because I am new to blender,
I'd appreciate some insight.

I've created a scene with my son's toy (you can find it at www.jamu.cz/kavani/stucked.zip ) and all I need is to set the
camera to follow the circle (as already done).
Problem is that if you watch ctrl+a in top view carefully, camera focus (for some strange reason) gets off the centre of my circle. I know I am dumb, but can anybody please explain it to me?

Or if you know about better way how to solve this situation? This
occured to me to be the fastest method.

Thanks a lot

Jan

try to use some object to track the camera view direction. select camera, shift-select object (maybe empty) and press ctrl-t to make the object track the camera's rotation. maybe you'll have to use alt-r on the camera to clear it's rotation if it point to somewhere you don't want it to point.
