It is important to see highlighted features on the map, however in QGIS 1.7.4, highlighted features can be visually obscured by other features where they overlap. This is as a result due to the ordering of drawing features on the map canvas.

For example, creating a PostGIS 2.0 table:

create table stacked_points (id integer primary key, geom geometry(Point,4326));
insert into stacked_points(id, geom) values(1, 'SRID=4326;POINT(1 1)');
insert into stacked_points(id, geom) values(2, 'SRID=4326;POINT(1 1)');

When viewing this in QGIS, it appears there is only one point, which is expected since the points overlap. However, when each feature is selected from the attribute table, only the bottom-most feature is visually highlighted on the map canvas, since it is the last drawn on the map canvas. The first feature (or any other features beneath) cannot be highlighted on the map canvas, as it is masked by the non-highlighted feature.
