color=#0000ff size=2>Have you checked the tolerance and toleranceunits of the
layer? For example, if you set tolerance to 4, and your units are degrees
(rather than pixels), it would apply about 400km, which would be a lot. Then it
may end up returning everything in your map. So maybe set toleranceunits to
pixels, and the amount to something sensible, and try again.</FONT></SPAN></DIV>

a query an Postgis Layer.<BR><BR>In my Postgis Layer there is a tablespace
with more than 1000 rows. Every row is a line on my map.<BR>When I click on a
