Thank you for your response.  
It's nice to know the center option is still available upon exporting, as having an origin centric scene is almost a necessity for my group.
As for the RMB issue, I went back and took a look at the log after recreating the problem and it shows nothing.  I'm not getting any errors or anything, it just stops responding to inputs.  I even tried redownloading the executable from ESRI and trying it there, but I get a similar problem.  I still have an academia version of 2010.3 that I'm working with, and I dont have the same problem there when working on the same files.
EDIT: I just confirmed with a co-worker that the same problem is plaguing his Macbook as well, once again striking from a fresh install.  So this is no longer an isolated incident.
