[postgis-users] itemnquery limitation

[Armin Burger]

Dave,

thanks for the hints. You were right with both your assumptions:

When doing the 'select by rectangle' I add a dynamic layer to highlight
the selected features adding all shapes found. This function uses the
shape index to identify these shapes. Disabling this sort of highlight
everything works well.

I searched and found an older version (March 2002) of libpg.dll that was
in the search path before the newer one. Using the newer one (from
February 2003) the problem disappeared completely.
