Thank you for your time & attention! Ron, you are correct, no ground wire. Also, I have not touched these outlets for some time, so I do not think that it's a matter of a disconnected wire. I believe (and hope, since new receptacles and switches are cheap), that it is just a bad unit. I will replace them tonight and test. Assuming my wife doesn't drag me to the mall again for some 'last minute shopping', I should be able to take care of it tonight. If so, I will post-up again tomorrow to let you know how it went.
