I installed OS 9 on a 99 Bronze key PowerBook and it generally works well. However, I have two problems when trying to wake it from sleep mode. First, the sound output rarely works after sleep--I have to reboot to make it work again. Second, if it has been asleep for an extended period, I sometimes lose the finder when it wakes. Interestingly, the applications will still be present, but no finder icon. As I succesively quit the applications, I can sometimes have the finder reappear after I quit the last app, but it doesn't work. So, I have to reboot the entire system. I had been using Multiple Users and wondered if that was the culprit, but the same problem occurs even with that disabled.
This is distressingly like the old 7.6 problems. Any ideas?
