[away3d] addOnMouseDown bug for loaded *.3ds module

[Valts Darznieks]

Hello I have the following code to add mouse click event to my 3d
module, but the event only works on some specific part of object, only
on bottom area of object, if i click on top of it then nothing
happens !
Any suggestions ?
Thank You !

model = loader.handle as ObjectContainer3D;
model.scale(2);
model.rotationX = 90;
model.addOnMouseDown(onClickModel);
