EntityBox weirdness

There seems to be a discrepancy between the origin of a mesh and the zero-points of the same mesh as applied to the function EntityBox. For instance:

	width#  = MeshWidth(Entity)
	height# = MeshHeight(Entity)
	depth#  = MeshDepth(Entity)

	x# = EntityX(Entity)
	y# = EntityY(Entity)
	z# = EntityZ(Entity)

;Draw a ghost box around the mesh
	cube = CreateCube() ; Cube starts as 2x2x2
	ScaleEntity cube,width/2,height/2,depth/2
	PositionEntity cube,x,y+height/2,z
	RotateEntity cube,EntityPitch(Entity),EntityYaw(Entity),EntityRoll(Entity)
	EntityAlpha cube,0.3
	EntityParent cube,Entity

;The ghost box perfectly encloses the mesh

;Set corresponding bounding box
;Same parameters as ghost box
	EntityBox Entity,0,height/2,0,width,height,depth	; wrong!
;But it doesn't work

;Translate the y and z coordinates by 1/2 their value
	EntityBox Entity,0,0,depth/2,width,height,depth		; right!
;Now it works!

The above code applies to a mesh with the origin at the bottom center.

But... no matter where the origin is of a mesh is placed, the same parameters that create a _visible_ bounding box should create a _pickable_ bounding box - but they don't!

Can anyone explain this?

Thanks... and be careful when using EntityBox!
