Just tried the following request: http://localhost:8080/geoserver/wms?HEIGHT=550&WIDTH=429&LAYERS=tiger%3Apoly_landmarks&STYLES=&SRS=EPSG%3A4326&FORMAT=image%2Fpng8&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&BBOX=-74.07079%2C40.661263%2C-73.884215%2C40.900463&transparent=true in both firefox and ie7/win xp and ie7 Vista, works fine in both, no black areas here... I don't have access to and older IE unfortunately... Cheers Andrea _______________________________________________ Dev mailing list [email protected] http://openlayers.org/mailman/listinfo/dev
