Problem with GrADS version 2 ????

[Mald MM5]

Hi there,

This is the problem I have encountered.

I had a post process file from a WRF output via the module arwpost. First I
use the GrADS version 1.8 to open the file ctl file it is working fine. It
opens and I can display the variables too. But due to the precision problem
in grads version 1.8 I was unable to give a point location which was giving
me the error that world coordinates are converted to non-integer grid
coordinates.
So I switched to version 2 and now for any field I try to display it gives
me "Notice:  Automatic Grid Interpolation Taking Place. Cannot contour grid
- all undefined values" and on the display it gives "Entire Grid Undefined".

When it opens the file in either version this is a notice it gives:
"Notice: Implied interpolation for file synNE_withtopo.ctl Interpolation
will be performed on any data displayed from this file"

How could this be cause version 1.8 was displaying the same field at the
same time.

Any idea what is going on? anybody?.....Is this a problem with version
2..probably not...
Here is the .ctl file...
