I have an existing fla project. I need to add a preloader screen to the project. Can anyone give me a suggestion on how to do this. I have found several preloader's but when I try to add to the existing fla, the preloader does not work. I am adding the additional layers for the preloader to the top of the timeline and I move the existing movie frames over ~10 frames (to the end of the preloader). When I run the movie, the preloader does not run but the movie starts immediately. Sometimes the preloader shows up after the movie plays.
The movie that I am using is a rather large file and my customers that are on slow connections will not like not seeing anything happen while the movie loads.
