[GRASS-user] attribute info attached to multiple areas

Hi,

I'm using WinGRASS-6.4.0SVN-r38537-1 (on Windows XP) and imported a
.MIF/.MID files via v.in.ogr using default settings. I get the
following message

"6 areas represent more (overlapping) features, because polygons
overlap in input layer(s). Such areas are linked to more than 1 row in
the attribute table. The number of features for those areas is stored
as category in layer 2."

I've identified one of these (overlapping) areas and found the vector
data contains an area completely surrounding another area. The problem
is the outside area's attribute information is also being attached to
the inside area - how can this association be removed as the inside
area has it's own attribute information?

Any help would be appreciated.

Thanks,

Sharon
