[R] problem with postscript output of R-devel on Windows

[Kimpel, Mark William]

I have developed a problem with the postscript output of plot on Windows. My code still works properly with R 2.3 but, with R 2.4, the white text on red background does not show up. It does, however, show up when output is sent to the screen. Below is my code and sessionInfo.

R version 2.4.0 Under development (unstable) (2006-08-29 r39012)

fileName<-paste(experiment, contrast, "FDR", FDR, "Graph", "ps", sep=".")
    postscript(file=fileName, paper="special",width=width, height=height) #set up graphics device
    plot(result.gN, layout.param, nodeAttrs = nAttrs, edgeAttrs = eAttrs,
        main=paste(paste("Experiment:", experiment, ";  Contrast:", contrast,";  FDR:", FDR, sep=""), paste("Min. connections ==", min.edges, "Min. citations per connection ==", min.cites, "Additional search criteria:",
            termAdditional, sep=" "), sep="    "))

Thanks,
