Newbe button question

Hello Everyone,

This is my first post, and please bear with me if this question sounds too ‘beginnerish’.

I have made an animated button - animation gets trigger on the rollOver state. When my button is clicked, I would like my button to stay on the ‘down’ image, and the button to be disabled. And as you press on other menu buttons, this button to be re-activated…

Almost every flash site I’ve visited has this feature with their buttons, but I can’t figure it out for the life of me. I couldn’t find any tutorials that cover this feature either…

Thank you for reading my post, and I’d really appreciate your help!
