[R] RGtk2 drawing area as cairo device - no points

[François Rebaudo]

Hi,
The following code adapted from Michael post (https://stat.ethz.ch/pipermail/r-help/2012-March/306069.html) works just fine on Linux Debian, but not on Windows 7 (no points on plots 2 and 3). More surprisingly, if the
first plot is a boxplot, it works on both OS... and if I do a pdf (using pdf()), I get my points... Thanks in advance for your
help.

library(RGtk2)
library(cairoDevice)
win = gtkWindow(show = FALSE)
win$setDefaultSize(500, 500)
da = gtkDrawingArea()
asCairoDevice(da)
win$add(da)
win$showAll()
layout(matrix(c(1,1,2,3),2,2,byrow=TRUE))
par(mar=c(0,0,0,0))
plot(1:10) #boxplot(1:10)
plot(1:10)
plot(1:10)
