Hi, first of all let me say you've done a very nice program, sometimes a spend time floating planet to planet and star to star. I like it very much.. So I want to roport some bug to help you improve it..
1) If I go from on star to another, (mouse then G), it happens that solar system browser becomes empty. No earth, mars, etc....
2) sometimes there is a problem of occlusion with orbits... For example if you are looking a moon of Jupiter, the red orbit lays behind jupiter, instead of in fornt of it.
3) Movie capture doesn't work. I grabs just the first frame, then window content becomes black and I have to restart.
I hope this may help you.
Bye
