Diskutility Won't Create Image From Cd


I recently upgraded to Tiger and now cannot use Disk Utility to create a disk image from a CD. The available options under "New" include "Blank Disk Image" and "Disk Image From Folder...". However the option "Disk Image from (Select a Device) is greyed out when I select either the CD or the drive. And yes, there is a disk in there :) Any ideas how to fix this?

I'm using a PB 12" (1.25Mhz) with CDRW.

Thanks in advance.
Yes. Ignore it, and use the "Disk Image From Folder..." feature. When prompted, simply click the icon of the CD once, then click the "Image" button.
