[winGRASS] new location with EPSG fails with my selection

[fiorenontaglio at libero.it]

Hi everybody,
I've read Wingrass has got some problems with locations made via projection values but I never read about problems with EPSG codes.

Infact it's easy to define a new location in this way, except for my case: EPSG code 26591 or 26592 (Italy zones):

If I enter these codes and then I go to Grass
an empty window of CMD.exe opens and remains but no other result.
If I shut down the window this message appears:
"Error: A datum name rome40 (Monte_mario) was specified without transformation parameters", detailed info are:

---------
Now select Datum Transformation Parameters
Please think carefully about the area covered by your data
and the accuracy you require before making your selection.

Enter 'list' to see the list of available Parameter sets
Enter the corresponding number, or <RETURN> to cancel request

I tried to specify the Helmert parameters in the EPSG code but it's the same

Thank you
