Using 10.1, ArcCatalog, personal geodatabase with two feature datasets.
In one of the feature datasets I am able to delete the dataset or any of the feature classes within that dataset but when I try to delete the other feature dataset or a feature class in it the Delete is grayed out. Is my GDB corrupted or a bug, or??? There isn't a lock on the database either when I'm trying to do this.
This is all occurring in the BISDM3.mdb I downloaded from Esri.
