problems with orthographic projections

[<Mark.Collier@xxxxxxxx>]

Hi,
In the following script I see the correct result in the 2nd window
(which is approximately centered at 140,-15 to compare) but the wrong
result in the 1st window. The field does not seem to be plotted at the
meridian that I specify, however, the land overlay looks in the right
spot.

Is there something obviously wrong with my syntax?

Interestingly it plot o.k. (for a split second) but then a second fill
overlays the result almost immediately.

Thanks,
Mark.
