No information from the player encyclopaedia, e.g. photos in the notation window, are displayed although use of the menu File-Options-Player Encyclopaedia is activated?
Start ChessBase and select a GM game from one of the database lists between two well-known players. Under the menu "View" click on "Players Photos" so that a tick is displayed.
Instead of a small picture a large photo will immediately be displayed (including I.D. card and a series of other photos) e.g. Carlsen at various stages of his career (from childhood to world champion).
With a chess game loaded you will find under "View" many interesting options e.g. direct activation of the reference display or book analysis.
