mpMinLonF around 0 degrees

Dear users,

I have a problem to configure a domain where the mpMinLonF is negative
(degrees west), and the mpMaxLonF is positive (degrees east): when
this is the case, the map entire world map is drawn.

I read data in with "fbinrecread", and configure the longitude as follows

   lon = ispan(0,480,1)*0.05 -6.
   lon!0 = "lon"
   lon_at_long_name = "longitude"
   lon_at_units = "degrees_east"

Then, when I use

res_at_mpMinLonF = -6.
res_at_mpMaxLonF = 18

, the entire map of the world is drawn (in horizontal direction).

However, for

res_at_mpMinLonF = -6.
res_at_mpMaxLonF = 0


res_at_mpMinLonF = 0.
res_at_mpMaxLonF = 18

everything is fine.

I also tried to set the area via mpLeftCornerLonF and
mpRightCornerLonF with the limit mode set to corners, but I still get
the entire world map drawn.

In the attached image, you can see that the x-axis is set to -6 / 18,
but the entire world is drawn.

Hope my question is clear.

I would appreciate any hint!
