This works fine for me.

I assume that you somehow managed to use an old version of
"grid" or "lattice" instead of the ones that ``come with R 1.8.1''.

Can you try to look at 
    .path.package()

after library(grid) ; library(lattice) 
and make sure that both packages come from the same place as
"base" e.g. ?

Dear R users,

I have changed my R version to the new 1.8.1 and some problems appears
when using the previous levelplot code.

This is a simple example:

a <-1:10
b <-11:20
j <- rnorm(100)
grid<-expand.grid(a = a, b = b)
levelplot(j~a*b, grid)

Normaly in my previous vs this was suffice to produce the levelplot.
Now, an empty  R graphics device appears with the following error
message:

Error in grid.pack(frame = key.gf, row = 1, col = 1, grob = grid.rect(x
=rep(0.5,  :        unused argument(s) (frame ...)

This shouldn't happen (and doesn't happen for me). What OS and what version 
of lattice are you using ?
