Hello all,

I have just been evaluating xmcd on our Digital UNIX V4.0 workstation and
I am pleased with the friendly interface. The installation of the
pre-built binary went smoothly. However, upon quitting xmcd via the 'power
button' I could not re-run xmcd (or any other CD player or mount a CD)
since it seems to produce lots of SCSI errors (CD is a DEC RRD45). Below
is the error message produce with DECevent:

Any ideas what's going on? And how I can solve it. The same thing also
occurs if I compile the source code.

Regards,
Rich
