I am having a problem getting Heat Map Widget 3.6 working with a secure service that already works in version 3.2. I have updated config and widgetconfigs with proxy info but when the widget opens it always prompts for secure login details. When details are entered it works as normal. I am using the standard mxml and compiling it using Flex 4.6.0 and agslib-3.6-2013-12-13.swc. We are using ArcGIS Server 10.0 for map services.
