StartupDisk preference in OSX bombs


I installed OSX Puiblic Beta on my bronze 500Mhz PB G3 with 12GB drive 256MB memory onto same HFS+ partition as my existing OS 9. Everything was working great, than today I was unable to boot back into OS X. The startup disk preference crashes everytime!! I select. Other preferences work fine like network, monitor, sounds etc..etc.. I tried to find the prefence application(not sure if it is a true application) on the OSX install CD but couldn't.

note preferences in OSX is the equivelent of control panels in OS9.

thanks for any info.

peace out
This is usually because a Mac OS 9.0.4 CDROM is mounted.
The Mac OS 9.0.0 CD doesn't cause this.
