  options(guiToolkit = "RGtk2")
  w        <-gwindow("GUI")
  g        <-ggroup(cont=w)

There are some hidden arguments for ggraphics under RGtk2. Try passing no_popup=TRUE to the ggraphics constructor. If you want to remove rubber banding, the argument to pass is do.rubber.banding=FALSE (why . for one, _ for the other? don't ask...)
