From Laurens Voerman, "just like ClusterCullingCallback (fixed in r14322) visual studio likes an explicit implementation of run() for InteractiveImageHandler.

The warning is (14 times):
include\osgViewer/ViewerEventHandlers(542): warning C4250: 'osgViewer::InteractiveImageHandler' : inherits 'osgGA::EventHandler::osgGA::EventHandler::run' via dominance (src\osgViewer\StatsHandler.cpp)
          include\osgGA/EventHandler(45) : see declaration of 'osgGA::EventHandler::run'


attached a zipped version of include\osgViewer\ViewerEventHandlers"
