I would suggest you insert the flash movie to
play independent of the slide and have the slide advance by user. A Flash movie will always display on top of the slidex.swf file so text on the slidex.swf file would not be visible.
The only way I think you could work around that, and this is not something Articulate would support at all would be to make your Flash movie the "slide master" swf for the slide you are using. So what you would need to do would be this:
1. Create a unique slide master for that specific slide where you want the Flash movie.
2. Preserve the slide master.
3. Publish the presentation.
4. In the data\swf folder you should have a bgdxxx.swf file. This is the swf used for the slide master.
5. What you would need to do is create your Flash movie at 720 x 540 to match the dimensions of the slide master.
6. Rename it to match the bgdxxx.swf file and swap it out.
7. Theoretically, now the text you have animated on the slide will display on top of the inserted SWF.
I've never done that but I don't see why it couldn't work.
