Yeah - late to this, I read it earlier on my phone, but that isn't the
replace to reply in full - Chris pretty well handled it.

The "real" issue appears to me to be a flaw in the code for the
installation - I believe it gets a full list of available resources, but
only presents the last one. The pull-down list DOES pull down - but
contains only one entity - and that happens to be the last disk in the
chain - no matter how many there are.  Back in PASCAL class, we called this
an OBOB - Off by one bit. Well - maybe if you tilt your head a little....
