Hi Robert,
what seems strange to me is that I add other event handler like for example
a custom stats handler or a osgGA::StateSetManipulator wich are derived from
the same class as the LODScaleHandler (ie: osgGA::GUIEventHandler). And with
those 2 others event handler everything is working fine, it only crashes if
I add the Lod handler.
I agree with you that this class is not very complicated but I do not
understand why this one fails to unref.
I try to track down the bug but I'm not sure it's on my application side,
I'm unable to find the difference between a simple LODScaleHandler and a
simple StatsHandler for example.
Kind regards,
