as2,cs3 problem with attachMovie and onPress

Hi,

I’m newbie… I have a movieclip with onPress and I attach another movie to the first one. Unfortunately, the second movie inherits the onPress function from the first one. How can I remove the onPress function from the second movie? I tried to set it’s onPress and onRelease to null and undefined but no success.

Thanks in advanced!

PS I’m using AS 2 and CS 3.
