Surely this is not a MacOS X issue but an X11 one.  People don't  
usually run X11 on notebooks.  So it only tends to arise with a  
Powerbook.

Of course the solution really does lie with R.app, but it is also non- 
trivial.  Since the introduction of Tiger some months back, Tcl/tk is  
a standard part of MacOS X.  The problem is that R.app is not  
friendly to Aqua Tcl/Tk extensions of R.  So it would be good to fix  
this, if someone has the time, skills and inclination.  I have the  
last but I am very short of the first two.
