In that case, I would recommend getting your hands onto the lastest version of Casady and Greene's Conflict Catcher. It replaces Apple's Extension Manager and has piles of helpful features. It allows you to quickly and simply setup boot configurations to troubleshoot for conflicts. You can just click to go to an "OS9 Base" configuration with all the optional software disabled and see if LW is still causing problems. Then you can re-enable stuff in a controlled manor to find your problem.
