I tried the method you suggested. It definately helped. I also used the PANE, then PPAR command to reduce the number of nodes, which speeded up computation and also helped get rid of little imperfections.
I've attached an image of the latest results. Much, much better!!!
Thanks again. You have been a great help!!!

Type "!" as often as needed to smooth the airfoil sufficiently. Looks like yours will need at least 10 repeats.
