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.

>>> 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?
