MouseClick trough a vector shape not working when there is a bitmap below it?

Question

Hello, I got something strange going on.
I have one class called Person that extends a Sprite.
First i have a bitmap that i add to the sprite class:
This bitmap is a transparent PNG.
addChild(_imageBitmap);
then i did some drawing in Flash that has the shape of this person and extended this to
the SimpleButton. This way, only the edge or the inner shape is clickable.
then i add this shape to this Person class too.
addChild(_personShape);
This way, the shape is on top of the bitmap.
Now i have an clickable item behind this person. This item is visible because it  is in the
transparent area of the bitmap and shape.
This clickable item does not respond on the mouse click! Only when i disabel the imageBitmap
(I tried uncomment the line addChild(_imageBitmap) and then it works just fine!
This means that the bitmap is causing the problem to get a click trough.
Is there a propertie for a bitmap like MouseChildren = false? or something else to make use
of a click trough within a shape?
Regards,
Chris.

Hello Ned,
Thanks for the advise, but i already tried the mouseChildren properties.
The bitmap has no property mouseChildren, so i created a new Container (sprite) and added
this bitmap to it and set the mouseChildren property to it. and the MouseEnabled too, but nothing happend differently.
The strange thing of this, is the fact that the rollOver and the RollOut item behind the bitmap image works just fine.
It has probably something to do with the fact that the clickable item is an displayObject3D (Papervision)
But what i also don't understand is when i don't use this bitmap, and only the vector shape it works just fine.
So i did a little trick, i did a break apart from he image and cut out the shape of the person with the lasso tool.
And i replaced this with the image shape and now it works.

Chris.
