[CentOS] Problem opening CD/DVD Drive door

Since moving from FC2 to CentOS 4.x I've been having a strange problem opening the CD/DVD drive door after burning backups.

A cron job tars and gzips directories I want to back up and stores the .tar.gz file in my /misc directory. I then burn the file onto a blank CD. All goes well with the burn...the drive door opens upon completion.

The problem occurs when I re-insert the CD to test the backup using File Roller. After reading the directories for verification, I find that I can not eject the disc unless I log out. This, obviously is a pain in the neck since I then have to restart several apps I normally have open.

Has anyone run into this before? Any suggestions?

Thanks, Dick
