Thank you, thank you, thank you. That worked perfectly. -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Robert Osfield Sent: Friday, January 21, 2011 3:58 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Screen Resolution Being Overriden in Twinview

To tell X11 to override the window manage redirect you'll need to set the Traits::overrideRedirect flag to true. Robert.
