Thanks for the tips. My Foriegn File Access Extension is installed, and as far as I know enabled. Is there somewhere I can check on this? I will install the utility you suggested, but the real problem is that I develop multimedia content that required the ISO 9660 format and the Enhanced CD format, and the inability of the new MacOS to read these formats put a big kink in the road for all developers like me. Can you imaging the "System Requirements" on the jewel case: "MacOS 7.6.1 or higher (except MacOS 9.04)." Why does Apple always have to screw with "the standards" and therefore screwing developers?
