visual cobol 2.3 show all copybooks not working

When you select this option it should expand all COPY statements in your program to include the copybook source with your other source.

On the COBOL toolbar in Visual Studio there is also a button for Show All Copybooks or Hide all Copybooks. Does this button also not work?

Are your copybooks included in your project or are you pointing to their location using the Copybooks tab of the Properties page?
