Please update your chimera to the daily build version, <http://www.cgl.ucsf.edu/chimera/alpha-downloads.html>. It has several bug fixes for Vista and Intel graphics. I would also recommend downloading the latest graphics driver from Intel, <http://downloadcenter.intel.com/> because, even with the chimera daily build, you may have problems due to an old graphics driver (no sideview for example).

Dear Chimera, I just installed Chimera on my Dell XPS 1210 laptop (Windows Vista; Mobile Intel(R) 945GM Express Chipset Family).

I get the following error everytime I start Chimera: Unable to turn reset multisampling. Graphics hardware supports request, but can not switch while maintaining display data.

Molecules are not properly rendered and does not hide objects rotated behind other objects. I.e., some object appear in front regardless of rotation.

This is a new problem. Chimera used to work fine on this computer. However, recently, I had Windows Vista reinstalled. Since the reinstallation, Chimera has these new problems.

Any ideas?

Thanks, Andy
