Rktmn,
I don't know where to begin...I thought this subject would have been covered time and time again at this site, by the Department of Redundancy Department.
As you know, it's not likely that I could explain this reasoning in four sentences or less, and, as with any concept that's perceived as "new" to this board, it's highly unlikely that I could convey this vital information without some pigeon starting a sh*t storm over the words I post.
If someone else would please answer this question for Rocketman, I would be happy to assist...
