The most common fix for chimera bugs is to update the graphics driver on your system to the latest version. If doing that doesn't fix your bug, then please send email to chimera-bugs@cgl.ucsf.edu with the information from the dxdiag program (specifically the System and Display tabs, but it easier to press the "Save All Information" button to save the contents to file and attach that file to your email). -- Greg On 12/13/2011 9:57 PM, Poornima Josyula wrote:

Hi,

I installed Chimera 1.5.3 in my system today. I have a Windows 7 64-bit machine with a processor that is, Intel i7-2600, CPU@ 3.40 GH

After I open the image, I get the following error. I copied this from the debug window of Chimera. * initializing general preferences loading Tix initializing graphics create application loading Pmw creating main window creating menus creating toolbar creating viewer initializing OpenGL initializing preferences initializing dialogs initializing COM initializing extensions Return code: -1073741819 Press return or enter to to exit*

I would be glad if anyone can help me fix this issue.

Thank you. -- With best regards, Poornima Josyula Ph.D. Scholar Fluid Mechanics Laboratory Dept. of Applied Mechanics IIT, Madras India E-mail: poornima.josyula@gmail.com <mailto:poornima.josyula@gmail.com>
