NERO Express - Entire Disk Copy

I use Nero Express to copy entire disks “on the fly” between my DVD drive and burner. With v6.3.0, and the previous version, the burner goes through an extended “spin” at the END of the “Lead-out”. It actually spins down and then back up 4-5 times before ejecting the finished CD. It never did this before. The burnt CD seems fine.

Any body else notice this? My burner is an ASUS CRW-4816A.

Thanks for any reply!
