Transferring to Form Application - Causing problems!

Hi there, I’m new, so please be gentle :?)

I’ve created a AS 2.0 Flash application in CS3. At the moment, it just consists of some buttons that animated when they are rolled over. Initially, I created these just on the timeline, and it worked perfectly.

Now I’ve tried to transfer them over to a Form Application (the application bit). When I test the movie, the buttons just start animating on their own. For some reason they don’t stop.

Any ideas how I can make them behave within the Form Application?
