Well, borders often come into play when we are working
with images and map projections, and if you say it is
fixed, I'll take your word for it. But something still
doesn't make sense to me about this... But I'm willing
to let it drop. I'm back in the US and the pile on my
desk is HUGE. I probably have better things to do. :-)

I don't think I said the wind bards "are pointing in
the wrong direction". I think I said "I don't know for
sure *which* direction they should be pointing in, and
I had received contradictory advice from people who's
job it was to know. So I let you choose which direction
pleases you. But, in any case, I think everyone who complained
was complaining about the direction of the staff, not the flags.

Cheers,

David
