I installed SpaceNavigator PE onto my Imac. It works well with google earth but is not recognized as a joystick for Flight simulator in google earth.
How I can I get it working for Flight Simulator
The Google Earth Developers who write the code for their application would be the only ones who could re-write the code to include use of a Space Navigator in their 'Flight Simulator' mode. If you have ideas of exactly how you would make use of the input from a SpaceNavigator in their application, you might want to contact them and share those thoughts with them.
