I have a UIPanel on depth 5 with a UIButton on it when you press the button I enable another game object with a UIPanel on depth 7 that gets moved over the top of the UIButton. That has a number picker on it that uses a Box collider with trigger on it to know I've pressed the number picker.
So collider on top of a UIButton on a UIPanel with a lower depth than the collider.
Problem is When I press on the collider it's not seen and the button underneath is pressed instead. in Camera debug mode you can see the object under the cursor is the button and not the collider on top of it. If I move the top panel picker somewhere else it all works fine.
So My question is why is the event system not obeying the UIPanel depth? What am I doing wrong?
