I've noticed that when burning BD-R disks via a USB DB-R drive, both the burning activity, and the verification activity will pause if the Toast application is not the "Active" application. When I toggle back to Toast, the activity resumes, but if it's running in the background all progress halts after only a few minutes. It will progress occasionally after that, but the only way I have found to keep the drive busy constantly is to make the Toast application "Active" (do nothing else). My power save settings have Computer Sleep set to Never. Any insight as to what settings could help would be greatly appreciated.
