I'm confused about what's probably a fairly simple concept.

I have a MC button in the library. I'm happy with it but I need to use several of them on the stage and customize each button I use a little bit...so I drag three out of the buttons out of the library onto the stage. I would expect that I can customize each instance I have dragged onto the stage, changing the colors, etc. but doing so modifies all three - like I'm modifying the library button itself.

How can I keep my 'template' button in the library then drag instances onto the stage that can then be individually customized?

What am I missing here??

Thanks
