R help - Jul 2008 - Unexpected line type in lattice plot key on pdf device

L.S.,
With the code below,
on the Windows screen the line types in the key show
   as solid and dashed as in the graph,
and in the pdf file they show
   as solid in the key and solid and dashed in the graph.
I would not expect that,
but may be I get something wrong.
Gerrit.

-------
library(lattice)
# pdf("pietje.pdf")
x<-0:10
xyplot((x^0.5)+(x^0.75)~x,type="o",lty=c(1,2),
auto.key=list(points=F,lines=T,columns=2, type="o",divide=1))
# dev.off()

I'm surprised that you see differences between windows() and pdf(). In
any case, the correct call would be something like

xyplot((x^0.5)+(x^0.75)~x,type="o",
       par.settings = simpleTheme(lty=c(1,2)),
       auto.key=list(points=F,lines=T,columns=2, type="o",divide=1))
