problem with new cd/dvd burner

I recently installed a new cd/dvd burner. Everything seemed fine. I
didn't realize until I gave a CD to somebody else that it did not
finalize the CD.

When burning CDs, I have always used windows explorer to drag the
files onto the CD and then write CDs. It worked fine with the old
burner. Is there a setting I need to change?

I looked at the properties for the CD drive, and didn't say anything
about finalizing a CD.

Thank you very much.
