NSView subview covering a control

Hi everyone,

What I'm trying to do is have a GUI that is contained in multiple
layers, contained in NSViews.

So I have roughly a background layer, a content layer, and a front
layer.

The content layer and the front layer both have controls on them, i.e.,
buttons, etc.

I can create them from NIB files, and swap out different NSView objects
from at each layer.

The one problem I'm having is that the topmost NSView is 'eating' all
of the mouse events that I want to go to the controls I've created on
the content layer of which the front view is a subview.

Calling setNextResponder to the content view on the front view doesn't
seem to work for me.

Is there a way to do it so taht if I don't click on a control in the
front view that the mouse event will be sent to the control that was
created as part of the content view?  The button is visible, it just
doesn't respond to clicks.

Any help would be greatly appreciated.
