Flash movie works under “Test Movie” but not when published.
If your flash file works correctly when you test the movie in Flash, but not once it is published, check your Publish Settings.
While modifying a flashcard example application I downloaded from Flashkit.com, I noticed that in development, using “Test Movie”, it worked perfectly, but once published, it had odd bugs.
On checking the publishing settings, I realized it had defaulted to Flash Player 7. Once changed to Flash Player 9, it worked fine. Apparently, some of my modifications relied on features that Flash Player 7 does not support.
