Sticky button, I don't think so, I must have used that CD drive twice,
only to run FreeBSD installation CD. Faulty hardware? Possibly, it
happens on both machines with tha mother board and never on others.

I am not running any of these, as far as I know, it could be an SCSI
bus reset? But then it is hardware and back to the above explanation.

Thanks anyway.
