matrix3D rotation being odd

1

Situation:
Hello, I’m trying to make a “room” in flash in which you can “move” around in.
I set up the room with flash cs4 3d functionality.

**SWF:
**http://www.swfcabin.com/open/1257388415
(use arrows)

Problem:
Rotation of the camera moves the room along X and Y axis.

**ActionScript:
**

var startX:int=room.x;
var startY:int=room.y;
var startZ:int=room.z;
stage.addEventListener(KeyboardEvent.KEY_DOWN,keyDownHandler);
function keyDownHandler(event:KeyboardEvent):void {

    var curX:int=room.x;
    var curY:int=room.y;
    var curZ:int=room.z;
    var cameraX:int=curX-startX;
    var cameraY:int=curY-startY;
    var cameraZ:int=curZ-startZ;
    trace(cameraX+" "+cameraY+" "+cameraZ);
    
    
    if (event.keyCode==Keyboard.LEFT) {     
        room.transform.matrix3D.appendRotation(10, Vector3D.Y_AXIS, new Vector3D(cameraX+startX,cameraY+startY,cameraZ+startZ));
    }
    if (event.keyCode==Keyboard.RIGHT) {
        room.transform.matrix3D.appendRotation(-10, Vector3D.Y_AXIS, new Vector3D(cameraX+startX,cameraY+startY,cameraZ+startZ));
    }
    if (event.keyCode==Keyboard.UP) {
        room.z-=10;

    }
    if (event.keyCode==Keyboard.DOWN) {
        room.z+=10;
    }
    

}
