7. Right click "child1", go to actions, and insert the action:

onClipEvent (load)  
{  
spring = false;  
startX = _x;  
startY = _y;  
spX = 0;  
spY = 0;  
_root.line._visible = 1;  
parentx = _root.parent._x;  
parenty = _root.parent._y;  
_root.line._x = parentx;  
_root.line._y = parenty;  
_root.line._xscale = _root.child1._x-parentx;  
_root.line._yscale = _root.child1._y-parenty;  
}  
onClipEvent (mouseDown)  
{  
startDrag ("", true);  
spring = true;  
}  
onClipEvent (mouseUp)  
{  
stopDrag ();  
spring = false;  
}  
onClipEvent (enterFrame)  
{  
parentx = _root.parent._x;  
parenty = _root.parent._y;  
_root.line._x = parentx;  
_root.line._y = parenty;  

//////  
_root.line._xscale = _root.child1._x-parentx;  
_root.line._yscale = _root.child1._y-parenty;  

//!spring = if false  
if (!spring)  
{  

//code to create the movements  
spX += (startX-_x);  
spY += (startY-_y);  
spX *= .09;  
spY *= .09;  
_x += spX;  
_y += spY;  
}  
}
