I just configured ViewCVS for my projects. It seems that in most cases the CVS
change log pages are hyperlinked just fine. But in some builds, some files are
not hyperlinked, for reasons which are not apparent to me. Look at

The first two lines are hyperlinked (both the rev # and the path), correctly.
But not the rest. Why?

The changelog.xml on the server for this build is also strange and wrong. Joelle
committed all six files at once, to the CVS HEAD. It shows five separate
changelog blocks; only the first, with two files, is linked. Of the four
non-hyperlinked files, two have <prevrevision> specified, of which one is
completely wrong (linking to a recent commit of the file to a named branch).

You can browse other builds for the project and see similar-looking problems (I
can upload changelog.xml files for them on request).
