Thank you, bjkg, for taking the time to help with my problem. I think my problem is hardware related. I have tried the lightscribe diagnostic utility. I am using Surething Deluxe labler software. It seems to be programmed for software problems. I tried the device manager troubleshooter. It was not for lableing.
I had this problem before. I sent the unit back and got a replacement. Same problem. I get the feeling some component in the unit is overheating causing it to stall or malfunction.
It must be time to try another brand.:Z
Thank you for your time and effort. I learn a lot from these forums.
