to disable it completely in xp you go to the control panel>administrative tools>services - from the list of services double click 'indexing service'>set to disabled.
you can also disable indexing on a drive by drive basis, by right-clicking on the drive in my computer>properties>unchecking 'allow indexing service...'. for instance my database is on one drive, my raws on another. i can turn off indexing for the databases this way but leave it active for the photos.
how this works in vista i don't know but i imagine it's similar.
He's basically beta testing for the rest of us.
Have you tried to reinstall the CS3 beta?
Worth a try.
