When this error first happened and I posted the results, I had seen an alert box come up before the problem manifested itself. I saw this same alert box come up again last night but instead of clicking OK on the alert and then clicking Finish, I decided to cancel all the work I had done so I wouldn't have the problem repeated that was associated with this original post.
The alert that I saw before the problem I described in this original post is shown in the attachment.
Any idea of what may have caused this?
