I am running MOSS 2007 and I am need of some assistance relating to Document Libraries and breadcrumbs. Let's assume I have a document library created. Within that document library is a folder which holds several sub-folders and each sub-folder holds files. If I browse to the document library itself and start navigating thorugh the folders, the breadcrumb updates automatically and shows me where I am in the library. If, however, I am using a web part page and I have displayed a Document Library Web Part, then there is no Document Library breadcrumb displayed. Is there anyway to display a breadcrumb which is specific to a web part?

Out of the box this is not possible. You would have to reference this webpart in custom code and add a bread crumb control somehow.
