Hi folks,

It looks to me as if I never had the extragalactic HII data.
But the .TDF Oliver supplied for the data references his sources
nicely, so I had no trouble in downloading it. If you grab

again, you'll get the 'exhii.dat' file this time.

I've heard from one other gent who also uses "Get A2.0 data
from CD-ROM", is asked for a disk, and then gets an "open file"
dialog. This is baffling me. I can't come up with _any_ good
reason for that to happen; Guide ought to just extract the data
from the specified disk, then stop. Still looking into it.

David, I'd not heard of the "re-arranged" A2.0, put onto
ten CDs instead of eleven. It looks to me as if with CD-Rs,
which can hold slightly more data than CD-ROMs, you could fit
A2.0 onto _nine_ disks. But Guide gives only disk numbers from
the A2.0 layout. As I was unaware of the alternative format,
Guide just asks for the "right" disk; it doesn't put up a
file dialog.

I also have no ideas on the odd "disappearing moon" problem.
If anyone has clues to offer on this puzzle or the A2.0 one
(such as "the bugs happen when I do _this_, but not when I
do _that_"), please let me know!

Some days, I get the bugs; other days, the bugs get me.
Today has been in the latter category.
