I must be a total idiot...instances from the library

Hey All,

Haven’t used Flash in a few months and came across an embarrasing problem. I’ve created the “up” and “down” states of a button in photoshop. I’ve imported those 2 images into Flash and created a button out of them.

So I’ve got this dummy button in the library. I dragged 3 instances of the button onto my stage. I now want to add different text to each button. Why is it that when I double-click on the button to edit it, the same changes affect the other 2 buttons?

Thanks.
