Like for any other problem with Mac software/hardware I would try the
following in the order mentioned:

1. Rebuild the desktop (use a utility like TechTool 1.1.2 (freeware) by
MicroMat, instead of the MacOS build-in option, as this will delete the old
desktop file, instead of rebuilding the existing one)

2.  Zap the parameter RAM (again use TechTool).

3.  Restart with extensions off (except the inits/cdevs neccesary for
CELLQuest to run)

4.  Reinstall BD software (remember to trash BD inits/cdevs and preferences) .

5.  Run a harddisk check program (better Norton Utilities, than Apples Disk
First Aid) from a floppy disk.

6.  Low level reformat the boot disk (internal harddisk), update the
harddisk driver and  reinstall system software and BD software.

Good Luck,
