I'm using Express Burn 4.05. Until today, it seemed to be working well; I spot-checked a few of the first audio CDs I burned, and didn't find any problems. The fourth disc I burned this morning, though, should have had 16 tracks totaling about 77 minutes. After an apparently successful burn(though too short considering the total length of the tracks), the CD contained only 5 tracks. These five tracks contained the music from the first 9 tracks on the list; these 9 tracks played in the right order, but were randomly broken up between the 5 tracks on the CD. I went back and checked the first three CDs from today, and they seemed fine. Anyone have any ideas? Thanks, Jeff
