Hi Mick,

I don't think I have ever produced a graph where the edges and nodes were
broken. But send the code and let me see if I or anyone else can reproduce
this type of behaviour. I am going to copy the bioconductor list because if
this turns out to be an error, then it would be nice to have this online so
the list would also know. Hope that is ok with you.

Cheers,
--TC
