Aloha Jambunathan K.,

Very many thanks for this information.  I have Org-mode version  
7.01trans (release_7.01h.880.g7531f).  I take it the problem I'm  
having is due to a relatively recent change to Org-mode.  If there is  
anything I can do to help isolate the problem, please let me know.

All the best,
Tom
