Re: How does one fix a Graphics3D display? (Solved)

I was contacted privately with a solution: Add the option 
ControllerLinking->False to the code below.  

I didn't think of this because the documentation made it sound like this 
would completely disconnect the SpaceNavigator from the DynamicModule, 
but this is misleading, as the direct use of ControllerState allows one 
to reach around the unlinking.

Thanks to all,

Joe Gwinn
