NAK for now. There was a reason for that, I need to remember, but I
think I have a weirdo case with the media-bay removable CD drive on
wallstreet that locks up the bus if you don't do something along the
sequence in there.

I have one of those machines in the office, so I should be able to give
it a go today to check, in the meantime, keep that patch on hold.

Ben.
