Well, I got the SpaceNavigator working. I had seen a reference to switching between it controlling the Camera View or the NavBall by hitting the ScrollLock key. I went looking for a ScrollLock Key when I noticed that the SpaceNavigator device was working for the Camera View. It turned out that my keyboard HAS NO stinkin' ScrollLock Key. (I was like when Homer Simpson was trying to follow directions to use a computer, and read, "Hit Any Key". "Doh! Where's the ANY key!?") In that "Other" tab you mentioned, there is an option to assign the ScrollLock key function to another key, which I did. I could then use the SpaceNavigator on the NavBall. :-) But, I still can't assign axis's myself. It appears that the game developers set up the SpaceNavigator inputs for what would work best for Aircraft flying rather than Rocket flying. Hopefully, we'll get some ability to change axis assignments in a patch. I'm finding that I'm still using the WASD keys for big movements, but loving being able to make small fine movements with the SpaceNavigator. Trying to do that with quick key presses was aggravating. I wasn't using any Beta drivers for the SpaceNavigator, just the latest driver from the 3dConnexion website. It just natively works in KSP 0.23; a little too natively, with the inability to modify the axii.
