Yes, I realized this during the freeze prior to R-2.6, and made some
temporary fixes which are part of lattice 0.17-1 (uploaded a couple of
days ago). This may or may not solve your problem. If not, please give
a reproducible example, as it would help me put a more proper fix in
place.

Note that in most situations, a whole new xyplot() is probably
overkill; just set suitable xscale and yscale for your viewport, and
call panel.xyplot().
