Sarah, 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. Regards,

I use it because I´m having similar task of yours. best regards Sarah ________________________________ Von: David Alda Fernandez de Lezea <[email protected]> An: Zac Spitzer <[email protected]>; [email protected] Gesendet: Donnerstag, den 7.

I know IE sux, but 95% of our customers have IE6 installed, and they are not allowed to switch to another version or to get other browsers. I get the polygons from GeoServer from a wfs layer. They are complex polygons with lots of vertices (parcels from cadastre) and I can't simplify the features because we are on the task of online editing using wfs-t protocol, so the edition must be accurate. I'm just wondering if there is something that I can show, like a progress bar or loading image, to tell the user this kind of operations will take a bit, but I'm afraid is going to be difficult because of the browser program. Any idea?

I know that this is a task it will consume some time, but the problem is that the browser gets freezed and I would like to improve that in order to improve the user experience. I've tried this in FF --> 5-10 seconds Safari --> 5 seconds Chrome --> 5 seconds Opera --> 5 seconds IE6 --> 60 seconds IE7 --> 40 seconds IE8 --> 30 seconds Is there something that I can do to improve the browser's response??
