Movieclip.startDrag...can someone please explain something to me?

The parameters for startDrag in clude a boolean value to lock the mouse to the center of the movieClip…I don’t understand what this means since I set the value to true, but I’m still able to move the cursor off of the movieclip while I am dragging it…does the lockCenter parameter mean something else? cuz I’d imagine that lockCenter means that the cursor is locked to the center of the mc…any clarification would be awesome! Thanks :hugegrin:
