[osg-users] AutoTransform cannot be picked up correctly

[OpenSceneGraph Users]

Thanks for your reply. I changed it based on osgPick, and since I only use 
OSG on Windows, I added those headers.

At present, I have no time to find out the problem. I have avoided this 
problem, and I will study it when I have time. Thanks again.
