Have installed version 5 and on startup the following message appears: "A file or device required for the operation of Sound 1 does not exist or is used by another process, or you have no permission to access it. The virtual machine will continue running, but the device will be disconnected" Just wondering what this means. I use Windows almost exclusively for running Dragon Naturally Speaking, and it al works fine under version 5 - nothing has changed. So what should I be doing about this error message - what has changed? Thanks Tom Using Macbook pro 15", 10.5.8, PD v5, Windows XP pro
