Shows the availability of 'page 117' yet clicking on it fails to advance the thread.
This phenonenon occasionally happened when someone deleted a contribution that was previously the first on the new page, but this rectified itself as soon as new contributions brought the additional page into use.
Can it be that several contributions have been removed from the above thread (as it is several contributions short of page 117)?
