hi.  
i had an earlier post about an interactive scene with bubbles. i’ve just updated the code and works quite well except the pin cursor that is meant to pop the bubbles is still not working.  
could anyone help?

here is the code:  
main class

from what i can see you never actually create the addPin event except for inside the function addPin.

thats like locking your keys inside your car, quite literally.

well unfortunately i use flash cs3 so chucking the code in to test it wont work.

You need to mode the addeventlistener to the main movie. you need to create the pin instance and add it from the main movie.

you can send me the files if you like and I’ll sort it from there.
