I think with the 'static' graphics model of R you are stuck with this
behaviour. I sometimes just force 'dev.set()' and another 'plot()'.

Switching to the JavaGD package / graphics device may help.  Speaking of
which, we now have rJava in Debian unstable [ and it installs fine on testing
] as package 'r-cran-rjava', so using these dynamic extension may now be
easier.
