Hi, Are you talking about the old osgviewerQT [1] or the newer osgviewerQt [2]?
[1] http://trac.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgviewerQT/osgviewerQT.cpp?rev=6819 [2] http://trac.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgviewerQt I remember having problem with the old one, but not with osgviewerQt. BTW, are you running OSG on Linux or Windows?
