Well, only things I can think of--and none of them may be right: (1) something wrong with the burner or the way it's installed; (20 something wrong with memory; (3) something with kernel (have you changed to a new one or recompiled recently); (4) something else you've added (either software or hardware or setup) lately. this list isn't prioritized--it could be any of the above, all of the above, or nothing even vaguely related to the above!!! -- Cheryl "Where your treasure is, there will your heart be also."
