How to Prevent Infinite Loop

1). Double-click the icon for the Flash item you want to alter. The file opens.
2). Double-click "Layer 1" and rename it "Animation."
3). Click "New Layer" at the bottom left of the timeline panel.
4). Click the red playhead in the timeline and drag it to the last frame of the animation.
5). Click the "Insert" menu, and select "Timeline" and "Keyframe."
6). Click the selection tool -- it looks like an arrow -- and click on the last frame of the animation.
7). Place your cursor in the text area next to (line 1) and type: stop();
8). Click "File" and "Save" to save the animation. It now no longer runs on an infinite loop.
