Hi Robert,

If you follow the link-to-the-post I have uploaded a sample geometry into that 
thread. The problem can be illustrated by using the osgkeyboardmouseexample and 
using the polytope intersector. Picking the "purple" cone is very inconsistent. 
The reason is that the "first" intersection sorted by distance is often not the 
cone ( when it clearly should be). The cone has a scaling transform - this is 
the root of the problem.

If you need more details and a verification of the bug I suggest emailing 
Daniel - he seems to be on top of the problem and a respected OSG contributor , 
but I gather the fix is complicated.

I have a workaround ( removing all scale transforms) but I would just hate to 
see the bug linger into too many versions....as it is a very tricky one.



Andrew
