I unloaded my.Net Framework before installing your latest burner and was pleased to find out that your program ran great on it's own with no .Net Framework installed. What third party installer did you use that packaged .Net support stuff along inside your EXE?? I looked on one on the market but it was way too pricy for me. I do freeware stuff for education using VB .Net. It's a powerful language. I see why you like it. BTW. My external Sony DVD RW DRU 510A USB would not allow multiple writes to the same rewritable disk. Hmmm?
