&nbsp;&nbsp; Hi, I've downloaded the chimera-1.4.1-win32.I am succeeded to run&nbsp;it for several times. However, the&nbsp;program had a error named as "Chimera failed abnormally; the exit code was: 1. use the --debug command line option for the full error message." and I can not start it anymore (same as Johan B&ouml;rjesson, <A href="http://www.cgl.ucsf.edu/pipermail/chimera-users/2005-November/000578.html">http://www.cgl.ucsf.edu/pipermail/chimera-users/2005-November/000578.html</A>).&nbsp; I notice&nbsp;there is a &nbsp;note in debug box "Type=screen distance must be positive",&nbsp;does it cause the problem? I am looking forward to your reply. Thank you very much.<BR>Best regards .<BR><BR>Qian Wang <BR>Zhejiang University, Hangzhou, China<BR>
