The question: "this has been slowly driving me crazy. 'every now and then', while in O, with several different objects created from a molecule, i run into the following problem when trying to identify atoms by 'clicking' on them with the mouse: I'll click on the atom, but I don't get the atom id'ed on that object. If I toggle on a different object which also has that atom, the atom id is displayed. This problem doesn't appear to happen all the time. I have no idea what is controlling this. Any solutions would be appreciated."
Alwyn dug into the code and came up with: "this was nasty to find. marilyn had 3 objects made called plc, plc_x and plc_y that were made from the molecule called plc. The bug comes if there are 2 object names where the second name is the same as the first followed by an undersore character '_' to work around it marilyn could call her objects plc, plcx, and plcz for example"
