Is this a bug? When a object overlay other one.

[nugao]

Hello, I get a trouble NGUI 3.0.2.

There's a gameobject A, it have only component BoxCollider, and its Children unactive. The other gameobject B is like A all children unactive. A and B in same level.

A's BoxCollider.pos.z == -0.01;
B's BoxCollider.pos.z == -0.02;

A and B are can click ,when a part of B overlay A, A is clicked and a child Sprite of A  is active, then the overlap part can't click to active B's  one child, the debug info last hit is still on A.

But first B is clicked and its a child is active, the overlap part is work all right.


I don't know how to fix it...I need some help.

I found change depth to fix my trouble, but why ?

Can Depth affect Z value of BoxCollider ?
