Dear Elaine,

thanks a lot for your promptest response!

I followed your advice and managed to get the problem solved by installing the last overnight upgrade.

Best regards,
Xavier

Dear Elaine,
I recently had to upgrade to Sierra from Mountain Lion and now I find that ions are displayed as black spheres only
in Chimera v. 1.9. Any ideas on what I should change?
Kind regards,
Xavier

Elaine, it's not only the ions, its all the atoms and bonds.
Ribbon appear fine though....

Dear Xavier,
I’m not an expert on this kind of thing, so I’m forwarding to the chimera-users list.

(Sending to the list is always recommended… I will still answer it if I can, just as fast!)

Although I don’t know if it’s related, maybe you should get a newer version of Chimera. Using Chimera versions 1.11.2 and 1.12 daily build on both a laptop and a desktop running Sierra, I do not have this problem. 

Best,
Elaine
