Thank you for offering to help. See my answers below...
Q. Are you using keyboard shortcuts or the File a Menu?
A. I'm right clicking on an object to delete it. The delete option is not
available. Also, I can rename it and copy it, but can't paste it.
Q. Is the db opened exclusively or could it be read only?
A. I have exclusive access to the database. Other users are logged out.
Q. Have you tried between multiple dbs or is this in the same one?
A. I have three Access dbs. Two of them are behaving this way since
the upgrade to Access 2010.
Q. Can you copy/paste single records?
A. Yes.
Q. Is the db in a trusted location, or has it been enabled. Did the warning bar appear along the top?
A. The db is in a trusted location. The warning bar doesn't appear.
