I created boot disks for my iMac G4 flat panel and iBook G4. That part went fine. I successfully ran Drive 10 on the iBook, which was my original goal. When it came time to restart the iBook, no go. I did a force shut down and discovered that the Apple menu restart and shut down options did not work at all. Then, to my horror, I found that the exact same thing happened to my iMac, and I didn't even use the boot disk. Just creating the boot disk resulted in the same problem as on the iBook. I have been emailing the developer for a day now but have not hear back. I have done all kinds of fix attempts, including running Cocktail, Disk Repair, Drive 10 (including surface scan) fsck, logging on with a different account, trashing preferences, resetting PRAM and NVRAM
