Hi Alja,

   Glad to hear that updating your graphics driver fixed the problem.  
When the graphics looks wrong on just one computer, it is almost always 
a graphics driver problem, not a Chimera bug.

>>> Dear Chimera users,
>>> I am trying to create an image for a publication using Chimera 1.6.1.
>>> Whenever I turn on "silhouette" dark spots appear on the screen and on the saved image. They seem totally random but they move along with the structure when rotated. When I zoom on them they look like small "umbrella-shaped" discs. The "show shadows" option is turned off.
>>> Does anybody know what are those spots and how to get rid of them?
>>> Thank you very much for any help.
