Softimage :: Focus Button On Property Editor

"The Focus icon updates to show the same type of property belonging to any element you select (hence "focusing" on the type of property). For example, if you display the Light property of a spotlight and then select a point light, the property editor is updated to display the Light property of the point light. However, if you then select a geometric object, the property editor is not updated".

Testing this out, it does not seem to work. Even when the focus icon is depressed it refreshes if I select a different type such as a mesh object after a light.

I have a simple scene set up to test it. A point light,a spot light and a cylinder. Basically the scenario in the description. It always refreshes in focus mode. Clicking on the mesh always gives me the mesh properties rather than sticking to the light properties which was selected first and Focus button depressed. Or clicking on a null also shifts to the null properties.
