Mac, I rebooted several times and tried it in Realband first so I know it's not a sharing issue.
John, it's interesting that you have the same issue with Win XP since that is what I am also running.
It is on a different usb port than the original installation but I have since reinstalled it on the other usb port. I will try going back to the original usb port and see if it does the same thing.
Won't have time to check that today but I will post my results.
Thanks for the ideas and assistance!
