This is my first trying on Drag n Drop function in flash. Please friends and Dr. Zaida, and Miss Farhana, take a look at my work. I found out that there was an error that made it cannot been drop. Just can drag but won't stop. It will only stop when I click on another object. The app can be view down here:

P/S: I've learned that the pivot point of every object should be in center to make it stop. I'll try it later and will post it in here. =)
