Thanks Pete Understand.. you know I had wondered about route changes. I had noticed the option regarding route change notification so I knew they existed but I never saw a flag so I presumed they were not occuring... alas I have been analyzing data on a different machine that running the pings (using the autosave files from the running machine as input) which begs the question is there anyway to visualize these route changes when looking at previously saved sample sets?
A point of clarification ... am I correct in asuming that when you click on a particular route change event that the top graph reflects the route after change event but the counts shown still reflect current sample window ?

thks,
Bob
