The screen you mentioned is the menu to login as a "user". Your computer has two user accounts, one with admin privileges, the other perhaps not, or meant to be restricted. Did you create these yourself?

Those were created as part of the initial setup of the computer, brand new out of the box. The administrator account would, in an office setting, be for the technical supervisor. It has powers that other users don't have.

Has this screen been displayed before?

Of course, every time I reboot the computer those two icons on that page appear. They are an essential part of starting up.

Did you then press Return to make it disappear?

In normal usage, clicking on DAVE loads things, and the next thing you see is the DESKTOP. DAVE AS ADMINISTRATOR is similar, but the desktop you see is specialized to serve just those functions that the technical director for the system can use.

Which of the two user icons was highlighted?

Neither. I click on the one I want to exercise. Actually, I've only once or twice clicked on DAVE AS ADMINISTRATOR, and then only out of curiosity.
