Your Chimera is dying too early for it to be a normal bug.  Since it is right after the "initializing graphics" message, please try updating the graphics driver to the latest from NVIDIA, and double check that your are using a 24/32 bit framebuffer instead of a 16 bit one (if you don't have a choice, then you're fine).  If that doesn't fix it, then please file a bug at http://www.cgl.ucsf.edu/cgi-bin/chimera_bug_report_2.py and we'll go from there.

Hi,
I have a Windows 8 pro machine, 64-bit 8 GB RAM Core i3 and Quadro FX 570.

When I start Chimera (x86 and x86-64), I see the splash screen then it says "pythonw.exe has stopped working".  When I add --debug:

Cannot execute 'gzip': no automatic decompression of .Z files

initializing general preferences
loading Tix
initializing graphics




I managed to cause windows to try to send an error report, which captured these files:
C:\Users\dek\AppData\Local\Temp\WERF405.tmp.appcompat.txt
  C:\Users\dek\AppData\Local\Temp\WERF464.tmp.mdmp

if those are useful for debugging, I can provide them.
