Let's see here...
1) We have a "sticky" thread on HR 45, which the OP, in his haste to post his message, failed to read. Would have explained the whole thing to him.
2) We have discussed the NAGR in this
thread, which if the OP had done a search, would have pulled it right up... Second from the top, not counting this thread.
Closed for the 2 reasons above.
