Error #2048: Security sandbox violation: http://www.sjcog.org/FlexMapViewer24/index.swf cannot load data from proxy.ashx?http://gisweb.sjcog.org/ArcGIS/rest/services/SJCOG_ParkAndRide/MapServer/0?
Thanks Ivan.
We looking more closely at the proxy page and Crossdomain file to understand what the problem is.
It is strange that it works fine with IE. I did read somewhere that other browsers with the Flash plug-in might struggle with returned strings that are too long.
