I'm exploring the PSR 1620-26 system, and the orbits disappears while I move around. The typical distance between both stars are around few AU only, but yet the orbits disappears. There's a bug in the orbit display.

As far as I can tell, the orbit paths in this system are being drawn correctly. Can you give me a cel URL that I can use to see the problem? The orbit of A will disappear when it get's small, but I assume that's not what you're talking about.

Well, the orbits disappears as soon as I'm at a distance of about 5 AU from one component. At some position, I can see the blue orbit and it disappear suddenly. According to the distances and scale, this isn't normal. I should be able to see the orbits on a much larger scale.

It's working fine for me. All the orbits in the system are visible until I'm 27AU from the barycenter. Then the orbit of A disappears as expected for orbits with a small size on screen.

For example, I don't have any orbit visible at a distance of about 1.25 AU from the stars barycenter, whatever the viewpoint.

If I select the "b" planet, I can see the orbit at this viewpoint (distance of 0.5 AU) :

But if I increase a bit the distance, the orbit disappear totally (distance of 0.8 AU) :

And apparently there's a bug with copy/paste an URL in Celestia, on the Mac. If I copy an URL in Celestia, go to my web browser and paste the URL, going back to Celestia broke the URL in the clipboard ! I can't use anymore my own URL (except clicking the code I pasted in the web browser) !

Another example, in the same system :

I can't see the stars orbit, while I'm just at a few AU from them.
