[Chimera-users] Higher order

[hsosa at aecom.yu.edu]

Thanks Tom, Now I can change the colors on each chain.
Another issue is that after displaying the surfaces of a big complex (33 
copies as BIOMT entries) chimera seems to freeze for very long periods 
of time.  It may be related to not having enough computer power (Dual 
Xeon 1.4 GHz,, 1GB RAM,  Windows XP,  Graphics ATI Radeon 9550, Chimera 
1.3) ?.
