wiered edge identification

[GoogleCodeExporter]

I'm using rggobi (version: 2.1.8-4)with R (version: 2.6.2). Using ggobi to
draw edges between nodes and identify them, I saw some weird behavior:

In R, I call ggobi by the following command:
Mtmp <- matrix(runif(120), ncol=2)
rownames(Mtmp) <- paste("V", 1:nrow(Mtmp), sep="")
Etmp <- matrix(c(4,52,39,53,41,54,41,55,41,2), byrow=TRUE, ncol=2)
g <- ggobi(Mtmp)
edges(g$Mtmp) <- Etmp

Now, in ggobi, I make edges display using Ctrl-L and turn on Identify
(Ctrl-I). If I put my mouse cursor over the node "V4", an unrelated edge is
highlighted. 

Did I something wrong? I will appreciate your help.

Thanks,
Jong
