OK, this has to be something dumb. But I can't see it.
I created a brand-new (blank) Access database. Then imported a CSV file to create a new table. Now I want to delete the table. Delete is greyed-out in the context menu. Select and then the Delete key does nothing?? I tried creating a trivial new table manually...same thing, can't delete it!
This is not a case of Access 2003 user security getting in the way. I just created this database from scratch.
