I ran Allan Englehart's example and got the expected result on R  
2.11.1 with Mac OS 10.5.8.

Seems possible that this is specific to Komodo Edit/Sciviews-R. I  
tried getting that editor/system to work as an editing environment a  
year ago and formed the opinion that there were too many got-cha's in  
the specification of options and user environments. I gave up and went  
back to a less complex (and in my hands, less fragile) strategy. I  
would take your question to whatever support site is available for  
Sciviews-R. (I suppose it could be a Leopard vs Snow Leopard issue,  
but do not have the resources to investigate.)
