Peter,

thanks, yes, you're right of course. It was i think corrected in 0.4.1.

Sadly enough it seems that there is another serious bug in the 
0.4.1 windows R package, it cannot read any file formats with read.graph, 
so there will be also a 0.4.2 release soon, maybe just for the 
windows R package.
