If you have been using Flex 3.5, you might want to upgrade to Flex 3.5a. Yes, the ‘a’ after 3.5 is not a typo. The Flex 3.5 build has been updated to address an issue with Flex-based AIR auto-update UI packaged within the SDK. The related JIRA bug for issue is http://bugs.adobe.com/jira/browse/SDK-24766
All developers using Flex 3.5 are encouraged to upgrade to Flex 3.5a. You can download this new build from http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+3
Also if you are using a Flex build older than Flex 3.5 then you are definitely encouraged to upgrade and try the latest builds. The milestone builds contain many bug fixes..
We are always interested in hearing from you, regarding the feedback. Also if you run into any bugs you can log them at http://bugs.adobe.com/jira
