What is the best way to handle behaviors that extend beyond the end of the timeline like the two Fade In/Fade Out behaviors in this screen shot? When I added the behavior the layers were too long. I shortened the layers by selecting them and choosing "Split" from the Edit menu as this is the best way I know to shorten a layer that extends past the end of the timeline. The problem is that the behaviors didn't shrink with the layers. Thanks for your help!
