R 2.10 Line Type Issue...

Morning folks (at least here on the western side of the U.S.)... This morning I constructed a contour plot of some bivariate distributions I'm working with. When I attempted to add a second contour to the plot using a dashed line (lty=2), R immediately went off to la-la land, requiring a force-quit. I finally tied the problem down to this statement: contour(u,v,ci,levels=c(0.30),add=TRUE,lty=2)
Please specify u, v, ci in order to make your example reproducible for us. Thanks, Uwe Ligges
I tried specifying lty="dash" as well without any change. The plot works with no lty specification (but produces a solid line, of course). In researching the issue, I learned that the demo, "demo(graphics)", should produce a variety of lines on the first plot. On my system, the first plot is completely blank. My system: PowerMac dual-G5, Leopard 10.5.8, R 2.10 fresh install. I attempted re-installing with no change. Any ideas? Thanks... -=d
