Possible issue with o3djs.picking

[GoogleCodeExporter]

What steps will reproduce the problem?
I've been trying to adapt the scatter chart example to support picking via
o3djs.picking, but encountered a problem wherein I could only get some
objects to be selectable.

I've stripped my code down to a case involving the display of a single cube
at (1,1,1) - pickingProblem.html and the associated selData.js should
demonstrate the issue.

What is the expected output?

Cube selected with left mouse button should turn green and have details
displayed (use of the 'Deselect' button restores colour).

What do you see instead?

Cube can be selected on initial display, and following a few axis rotations
invoked with 'a'.  However, after rotating the object past the axis it can
no longer be selected. This is suggestive, but there seem to be other cases
where selection fails also.

As I'm a newbie to 3D graphics, there is a distinct possibility that I've
just missed something 'obvious' that I need to do to picking.js given the
viewing mechanisms I'm using (a possible additional inverse matrix of some
kind, perhaps).  If so, please let me know.

What version of the product are you using? 
0.1.42.3

On what operating system?

XP Professional Service Pack 3

What hardware are you using:  graphics card type?  
Intel GMA 3000

motherboard type?
Dell Optiplex 745

Problem is in my code, NOT in O3D - apologies for wasting your time.
