I have a RIA that has two skin swfs that it loads on startup. Around October of last year users running windows 7 have had the application halt on startup because the calls to loadStyleDeclarations never complete or error. They continue to work on other platforms, but on windows 7 (ie, chrome and firefox), I get StyleEvent.PROGRESS events (albeit just at 0 bytes and at total bytes completed) but I never get a StyleEvent.COMPLETE or StyleEvent.ERROR event. If I decide to continue after getting total bytes completed StyleEvent.PROGRESS event the application doesn't have the skins applied. Does anyone have any advice on diagnosing loadStyleDeclarations silently failing?
