ActionScript 2.0 :: Dragging And Dropping User-drawn Lines?

I'm working on a Flash project in which users are able to draw on the stage. Once they've drawn their lines and turned off the pen tool, though, I want them to be able to do something unusual. I want them to have the ability to drag and drop the lines they've drawn. I actually don't really care whether they pick up individual segments separately or everything together, but they need to be able to drag and drop in some way, shape or form.

The line-drawing code currently looks like this:

ActionScript Code:
onMouseDown = function(){
if (penOn) {
if (erased7 == true) {

[Code]......

When I make line7 draggable (by dynamically appending event handlers to the line after the user creates it), subsequent attempts by the user to draw lines cause the new lines to appear within the confines of the movieclip already created, no matter where the mouse button is pressed. The problem, as I've been able to determine, is essentially this: When you don't make the line draggable, the dimensions of the line movieclip expand every time the user clicks the mouse button. But appending the event handlers in effect freezes the movieclip, and its dimensions aren't changed after that, at least not by this code. I've tried workarounds, but no luck. I've also tried creating a new movieclip each time the user tries to draw another line, but that's failed as well
