Flash Animation 27: Flash for Web Design: Creating Scrollable Text

On your stage, right-click on your text box now and select Scrollable. If it's already checked, uncheck it and then check it again, just to make sure it takes properly after all the changes we've made. This will ensure that Flash knows that the box is supposed to scroll when those Actions act upon it. When the box is scrollable the little square at the corner will turn black instead of white.
