color=#0000ff size=2>Thanks for your response. I use it in my app, but I think
that in this case is not useful. The problem occurs, I guess, in the moment
of parsing the features in openlayers.layer.vector so during this task the
browser gets freezed like if it was not responding, after a period of time the
browsers zooms to the data extent and is then when it appears the OpenLayers'
loading panel, but it appears because of the zoom action not because of the
procces of parsing the features.</FONT></SPAN></DIV>

color=#0000ff size=2>I get the polygons from GeoServer from a wfs layer. They
are complex polygons with lots of vertices (parcels from cadastre)

editing using wfs-t protocol, so the edition must be
accurate.</FONT></SPAN></DIV>
