After exhausting my ideas I need advice. I am using ArcInfo 10.1 (with a concurrent license over a network). I add a shapefile to my project which needs some attribute editing. I start the Editor and open the Attributes window. But the window is blank except for two box lines. I have tried the same method on two other machines (both with stand alone licenses) with the same results. I uninstalled and reinstalled ArcGIS 10.1 but the results remain the same. I have tried the attributes editor from both a shapefile and and a geodatabase feature class; same results. I am baffled. Any else experiencing this? I have attached an example. Help!
