I’m trying to set up constrained occupancy groups in the GUI, but trying to add selections, the entire Phenix GUI crashes. This happens when clicking the plus sign in the dialogue attached. 

This is with the PHENIX-1.9-1692 build (updating from 1.8.x did not help) with OSX Mavericks (10.9.2). I know this worked before smoothly, so there perhaps is a bug somewhere.
