Dear Monnie,
thank you for your answer.
I Rgraphviz is always somehow problematic on windows computers.
I do not think I have to download Graphviz since it was never
necessary before on  packages compiled for windows. The strange point
is that I can load and use without problems the Bioconductor 2.1
Rgraphviz version.
