[away3d] TargetCamera moving problem

[Miroku]

Hi everyone,
I've got a problem with moving a targetcamera:
I have this very little piece of code:

                        public function render(e:Event):void
                        {
                                camera.moveLeft(200); //camera is a 
targetcamera targeting the
only object in the scene
                                trace(camera.z);
                                away.view.render();
                        }

when I run it I can see my object zooming out slowly.
I wrote the trace as a test and I verified that the z coordinate of
the camera changes!!!
Can someone tell me why this happens?
And how can I stop that?
I tried adjusting the coordinate right after the moveLeft but I had a
strange behaviour and so I removed it...

Hope someone can help me.
Thanx in advance =)
