Having identified the cause of the better smoothness in the older version, I'm going to put my efforts into other characterizations. The test source will remain on the server, but I'm won't do more with it unless someone finds it useful. -- Bill Davidsen "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot
