MovieClipLoader (MX 2004)
MovieClipLoader onGetProgress problem
Problem
onGetProgress fails to work and return any information in the flash development environment.
Solution
onLoadProgress only works in the browser plugin. Even simulating the download (Control + Enter, View > Download Settings > 'change to required download speed' and then pressing Control + Enter again (or choosing the Simulate Download option from the View menu) will not work. You will HAVE to publish the movie in a html page and run it to see it working.
