I wonder if you are playing the 32 bit version of the game as the floating white dot disappeared for me around the same time the 64 bit and Horizons were launched?
Nope, 64 bit Horizons. I have scanned countless NS and Black Holes on my voyage from the bubble to Colonia, through SagA* and now 37 Kly from start to Beagle and that was the very first time this happened to me?!
But it was unmistakably as described above (and very noticeable)! :S[big grin]
Very puzzling, maybe some spacefaring being of pure energy?
