In layer properties, I am drawing categories using unique values of one field.  All values appear but I am unable to edit (linetype, thickness, color, etc.) the symbol.  I double click and nothing happens.  I tried the exact same operation on another computer in the office and it works. I've tried restarting my computer, restarting ArcMap, starting a new project, etc.  Any help would be much appreciated.
