I have a 2 questions.

1. When a button is pressed I want for it to stay depressed (ie. maintain the
Down state). How do I do this? Then I want the user to be able to unselect the
button by clicking on it (kinda like the way a checkbox works). How can I do
this?

2. I want to set all my graphics to invisible when the movie starts. I only
want to show them when someone selects a button. How do I set all the graphics
to invisible initially?

Thanks!!!!

1. make your buttons into movieclip buttons. you can then control your (movieclip) button's timeline.
