This flash scrollbar will smoothly scroll just about any kind of content. Place everything into a movie clip, and you’re all set. It also includes code to load external content. Can be used with dynamic system fonts no problem. You can customize colors, etc and it will be much lighter than the components that ship with Flash.
The scrollbar is pretty easy to integrate. Open the fla, and copy paste into your project. I have used it numerous times in my projects. One example is the Auto Flash Gallery. Now it’s yours to use in your projects for free! Please note that this code is offered as is and I will not offer technical support or help with integration.
