Hi, > The Marshall Plan [3] was the nickname for multi-version support in Flex > [4][5] that also solved communicating between sandboxed applications.
Tour De Flex has no need for communication between it and any 3rd party app it loads so that's not a requirement here. From looking at the SWFLoader code, I think (but not 100% sure) it defaults to using the Marshall Plan (scattered though out SWFLoader), and that is a factor when working out the content size (getContentSize use of a SWFBridge to calculate size). Thanks, Justin PS Any chance you can format your email so that the URL don't break over lines and thus result in 404s?
