Short description of error
At the top of the properties window, there is always the path to the object being editted below. In this case: "Cube -> Material -> Material.BI". With a node material containing both, BI and Cycles nodes, there is the path of the BI material shown even though the current engine is Cycles and the properties below shows the Cycles material setup. Not a major issue, but the displayed path should match what is being editted.
