Hi everyone,
The "problem" was the result of my historical misbehavior of embedding
links within certain font enhancements. This used to work, but no
longer. Any of you package maintainers who find that your links are
suddenly becoming literal text on the HTML help pages are likely to have
the same problem. Solution - remove any \samp tags around the links.
Thanks to Duncan who provided the necessary info.
New versions of the clinsig, crank, plotrix and prettyR packages will
appear shortly.
Jim
