Ahhh, that all stemmed from the MOTU Nation users forum that had many users that were literally pulling their hair out trying to get Leopard to run correctly with DP and NI plug-ins and other 3rd party plug-ins. There were just SOOOoooo many variables. There were some successes, but the general consensus seemed to be "if it ain't broke, don't fix it." [:)]
But with the onslaught of DP7 (which I'm receiving tomorrw) things seem to be much more stable now. I love DP but it can be a bit "fickle" at times!
