Thanks Peter.
I noticed that when I was in “Terrestrial Sphere” mode, I had lost all my star symbology – the labels were visible but the stellar dots had disappeared.

When I switched to “Celestial Sphere” mode, everything looked okay; the star symbols were visible along with their labels for all the zoom levels I tried.
Hopefully this update should fix that problem? I’m using Open GL by the way.
Cheers
Dennis
