Many many tnx to you Jørgen. I see the problem: VML: over 50 feature it died...and i have 175 feature to show in the same time! I have tried to use strategies but seems to not work...peraphs for the present of labels..i will more tests soon. It's a very very big problem because i really need to show all the 175 elements to screen and after give the ability to the user to zoom in. Hmmm i'm thinking to remove the ability to the user to move around the screen when is in the max zoom-out... _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
