[top-posting fixed -- it's generally frowned upon in this 
newsgroup/mailing-list and adherence to the preferences will tend 
to get you a wider audience]

Are your issues with my code, or with the topic at hand?  If it's 
my code, note my comment about it being untested.  If it's the 
topic at hand, I recommend trying my code (or a variation 
there-of after you've tested it).
