[Chimera-users] Mac OS X 10.4.3 update breaks Chimera

Hi,
	The 10.4.3 update to OS X breaks a significant amount of Chimera  
functionality.  Attempts to use that functionality cause Chimera to  
exit.  In particular, for structures that contain residues other than  
the standard amino/nucleic acids or water, anything that directly or  
indirectly makes Chimera determine atom types will cause the  
failure.  Such things include adding hydrogens, finding hydrogen  
bonds, and going into ball-and-stick or sphere representation (the  
atom sizes are based on atom types) -- though stick-only mode is okay.
	We are working on a fix.  Until we have one, you will have to weigh  
the improvements offered by 10.4.3 against the loss of Chimera  
functionality.  I'll send mail to the list as soon as there are  
developments.
