Fixed.

2f43 had some matrices applied to one set of chains, and another set of matrices applied to another set of chains, requiring making a copy of the molecule, so one set of matrices could be used for each of 2 molecule copies. The copy code was broken due to changes a month ago to the AtomicStructure constructor arguments.

Fix confirmed, thanks!  One related problem (but unlikely for users to find, so perhaps low priority) is a traceback after the following:

open 2f43
sym #1 a 1
close #2
sym #1 a 1

Fixed again.
