 There are several usability issues with the current ground control points
 dialog on WinGRASS:

 1. When a point is selected in the map display, the cursor in the GCP
 dialog does advance to a new field to record the next point clicked. The
 user must manually click on a new field to select a new point, otherwise,
 the same point coordinates are overwritten and there will be more points
 selected than there are recorded GCPs entered.

 2. There should be a visual divider that separates each entry column:
 Coordinates, Geographic Coordinates etc. Currently, some users experience
 errors because they attempt to use the spacebar to move to the next field.

 3. When the user clicks on a point in the map display, the decimal
 precision of the clicked point can fill in the entire field up to the next
 column, confusing the user into thinking that there is no way to advance
 to the next field (geographic coordinates). This is resolved by simply
 clicking in the second column, but the cursor appears in the same
 location. This could also be resolved by resolving #2 above.

GRASS GIS <http://grass.osgeo.org>
Commonly referred to as GRASS, this is a Geographic Information System (GIS) used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS is official project of the Open Source Geospatial Foundation.
