David,

Previously I modified the internal navigation to fix the grid interpolation 
problem you were seeing
for vectors between grid points by creating a new grid subregion centered on 
the gpoint (eg so
the gpoint location would be on a remapped grid point and the vectors wouldn't 
be using interpolated
components between grid points).

In doing that, I created a new internal navigation, which is conflicting with 
the later query of
the user point back into the original navigation (now the new grid is a 3x3 
grid about the GPOINT
rather than the original model domain, so your GPOINT=@x;y is not defined in 
the new space). 
In fact, the output you are seeing for the GPOINT=lat;lon case should be 
showing a pair of
grid points in the new 3x3 domain now instead of the original grid if you look 
at that too!

I'll have to save the original navigation, and restore it after I do the 
interpolation
(I'll apply this to the gdpoint program as well since I made the same change 
there).

I'll get that done tomorrow (trying to beat the snow and subzero temps home 
today ;-)

Thanks for pointing this out.
