Cannot manage unique HydroID in ArcHydro

Discussion created by marzolff on Sep 21, 2011
I am using ArcHydro 2.0.77 for ArcGIS 10 (SP 2). I am trying to manage the HydroIDs by using the UniqueID Tables Manager from the ApUtilities Menu, but I can not add new Layer Keys. I right-click into the empty table as recommended by the ArcHydro Help and choose ADD, but nothing happens... in the ApUniqueID Table tab, the add function does work if I right-click not on an empty row, but on the existing HydroID row. But in the LayerKey Table, there does not yet exist a record, so this trick doesn't work... Am I doing something wrong or is this a bug?
Many thanks,
