I have a simple Flash movie which loads several external PNG-24 images into movie clips. Each movie clip is partially transparent (using alpha transparency), and made drag-and-droppable. Everything works properly except that for each movie clip, I am able to drag and drop the clip using the transparent space around the image. I want the “grab-able” area of each clip to correpond to only the non-transparent areas of the PNG, not a rectangular box around each movie clip. Is there any way to do this?
