NO issues at all now that I've fully crossed over to the newest OS.. no issues with drivers.. although.. it change all of my playback engine and i/o preferences.. that was fixed quick enough once I realized what it did.. it also changed my bit rate to something other than what 11R was set to.. but that came up in a dialog box when I was firing up a session and that was quickly fixed.

edited to add.. the only thing not right is that my dvd player won't play a dvd?.. weird.
