Macromedia released the basic set of Flash MX components that can be used in Flash MX 2004 and Flash Player 7. Here is the list of included components:
* CheckBox
* ComboBox
* ListBox
* PushButton
* RadioButton
* ScrollBar
* ScrollPane
Given that the new version 2 components are the preferred choice in the new environment, the purpose of this update is to address problems of migrating old FLAs with v1 components to the new player. Get them from Flash Exchange.
