Dear Chimera Developers,

Recently, I found something really annoying when I was using Chimera. The
problem is that when I use chimera to display CryoEM maps(400X400X400, 32
bits), my computer shut down automatically. I don't think there's
something wrong with the hardware and coot or pymol is fine. This is not
just an accident. It happened quite a few times, especially when I
suddenly zoom in, computer is suddenly shut down. Later there would be
some error massage related to the instability of the power, CPU self
protection "£$%^&# ...  when I turned on the computer again. But I don't
think there is anything wrong with the power as well, I've run other
softwares without any problem. Also, it happens to both Window 7 and
CentOS 6.5 in the same PC. So it's obviously hardware level issue related
to Chimera.

My guess is that there might be something in Chimera that activated the
self-protection of CPU or similar things.  Any ideas why this occurs and
how can I solve it?

Best wishes
