(haven't updated to 1.5.1 because it's not available on Mandrake 8.1 which is on my home machine)

using lattice 0.5-4 and grid 0.6-1 I am having difficulty getting 3 pdf files produced.  The following code only produces 2 files, test1.pdf and test2.pdf:

trellis.device('pdf',file='test%d.pdf',onefile=FALSE)
p1 <- xyplot(runif(20) ~ runif(20))
p2 <- p1
for(i in 1:3) {
 print(p1,split=c(1,1,2,1),more=TRUE)
 print(p2,split=c(2,1,2,1),more=FALSE)
}
dev.off()

Thanks in advance for any help.
