Subject: [R] lattice color problem with symbols: bug?

Dear useR's,

I have a problem with the lattice plotting of some symbols:

library(lattice)

test<-data.frame(x=c(2,3,1,5),u=c(rep(1,2),rep(2,2)),g=c(rep(c(1,2),2)))

xyplot(x~u,groups=g,
 data=test,
 par.settings=list(
    superpose.symbol=list(pch=c(22, 23),cex=c(1.7,1.6),col="black")
    ),
 key=list(
    text=list(c("t1","t2")),
    space = "bottom",pch=c(23, 22),
    points=F,
    cex=1.0,
    col="black"
    ),
)

As you see the symbols which have been plotted into the plotting area appear

to have some filling color while in the legend there is no filling color 
although the specification of the symbols is the same.

.........

Not for me. Both sets of symbols are identical and unfilled.
