I am using Nero InCD with Microsoft XP, with a Cendyne Burner. CD-R's burn OK. Some CD-RW's work fine as drag and drop. Other CD-RW's do not work. When opening My Computer, it opens blank and My Computer is Not Responding, so the CD-RW’s can not be opened. I tried CD-RW's from three different manufacturers and they don't work. On some I can format them, but then the formatted disc won’t open. My Computer goes blank with Not Responding. As soon as I eject the disc, My Computer opens. I was able to format a disc on another computer, and it worked fine on the subject computer.
