Humm. Well, I don't see any reason this doesn't work
perfectly. :-)

Liam is setting up the map projection for you (Mercator
in this case), and the wind barbs are certainly going onto
the map in data coordinate space. Makes me think you
are not doing the CURSOR command properly. Are you using
the DOWN and DATA keywords with it? And are you using
it immediately after you run this program?

Just don't have many other ideas.

Cheers,

David
