Just let me add some more observations about this problem.
I get the grid lines, but I don't get the coast lines. I tries the same on
another computer

IDL> print,!version
{ alpha vms 3.5.1}

And it works just fine there with the full outline of the coastlines. So. I
don't really know if it is a problem of IDL or of SPARC UNIX.
