R help - Nov 2008 - Possible bug in screen ?

Hi all,
after choosen the plot in witch I want to draw a point, just the first 
plot draws the point
Is it a bug or just a user-problem ?

Example :
split.screen(c(2,1))
screen(1)
plot(1:10)
screen(2)
plot(10:100)

screen(n=1, new=F)
points(4,3, col="red")
screen(n=2, new=F)
points(20,20, col="red")

screen(n=1, new=F)
points(6,6, col="red")
screen(n=2, new=F)
points(80,80, col="red")


Thanks for help.

Greetings

Before raising the bug flag, one should read the help page (more?)  
carefully:
--------
Warnings
The recommended way to use these functions is to completely draw a  
plot and all additions (i.e. points and lines) to the base plot, prior  
to selecting and plotting on another screen. The behavior associated  
with returning to a screen to add to an existing plot is unpredictable  
and may result in problems that are not readily visible.

It is an unpredictability:
