Don't use the default button. That's bad UI anyway. Add your own favorite button for each answer.

Don't use the default button. That's bad UI anyway. Add your own favorite button for each answer.

And, since you will be using your own classes, like:

<a class="myStarOff" href="#" data-ansID="1234" title="Click to add as favorite answer (click again to undo)">
favorite</a>

<a class="myStarOn" href="#" data-ansID="56789" title="Click to remove from favorite answers (click again to redo)">
favorite</a>

...and your own event handlers; there will be no conflict.
