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,&nbsp;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>
