3Dconnexion would like to have support for much more applications. But you will have to contact in such cases (as you already did) the editor of the software, as 3Dconnexion doesn't have access to proprietary code, and ask for integrating support. We have a SDK which every software developer can download (free of charge) and which allows the support integration in proprietary software.
So what is the difference in SpaceTraveler and SpaceNavigator. They look similar in size. I know the Taveler has programable buttons. is there any other major differences
