At some point in your Flex career you have probably wanted to get rid of the generic Flex preloader that you always see when your application initially loads. It’s an easy way for people to spot a Flex app and quite frankly is a lack of attention to detail. If your application is fairly light weight there really is no need for it and it’s super easy to make a custom one. Luckily the answer is simple. All you have to do is set the usePreloader attribute to false.
