Need help with random intro replaying on flash site buttons

i’ve created my first full flash site with flash mx 04 using the tutorial on this site (http://www.kirupa.com/developer/mx/full_site.htm) and added a few shape and motion tweens to spice it up a little.

but apparently i spoced it up too much. when i go to test my page, if i leave the cursor on the button too long or roll over it too much the entire intro replays.

any help for a rookie?
