The express burn will fail on subsequent copies of a file unless the CD Free Time is displayed on the bottom line of the window. Starting a burn before the CD free time is displayed will cause the session to fail. This problem is not present on startup as the main express burn window is not displayed until the disc is read. However whenever you put a disc into the copier make sure the CD free time is shown. Hopefully this "Feature" will be remedied in a later release.
