[F8] Confusing problem please help

i'm making this gallery of items and it snaps to the start of the scenes when i click on a button.
i'll show you what i mean:

http://moize.shah.googlepages.com/Flasher.swf <-- heres the SWF file
(click on the left arrow and then try clicking on a picture. The button is set to a different scene but why does it snap to the start)

Heres the FLA version, see if you can identify the problem:

I really need this finished today. I would appreciate it if some one could help me out.
Thanks
