AIR iOS app crashes

Hi everybody,

I've  been working on an iPad app in Flash and all went well but at the end I  discovered a problem. I'm making a childrens book with a page on each  frame. And a can move between the pages. On the pages things are  happening. Things can be touched and make sounds or can be moved.The  problem is that the app seems to be instable. After a while it crashes  and I have to start over again.

I did a lot of optimizing  as told at different blogs made sure all events are closed when I don't  need them anymore but it still crashes. Now I was thinking it could be the sound that is the problem. On each pages I load at least one sound some playing on click, endlessly looping when on the page. Could this give me a memory problem? I looked for sound and sounchannel close or remove options but couldn't find a right solution. I think it's easiest to put this remove sound stuff in the killMe function right? Here is a script I load everypage.

I'm working in Flash 5.5 with the AIR 2.7 SDK. And am testig on a iPad 3G.

Hope for some good tips or suggestions,

Thanks in advance.
