[R] Possible bug in screen ?

[David Winsemius]

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.
