I just upgraded my system from Windows 2000 to Windows XP Professional SP-3. After the upgrade, my CD & DVD drives will not eject with the button, or by right-clicking the drive and selecting "eject." The drives are recognized under Windows, and there is drag and drop function. I am not using third-party CD-writing software, such as Nero. I have tried enabling and disabling the record function on these drives, without any change in the ejection behavior.
