Anyone know how to dynamically change the border of UILoader Component

Question

Hi All
I am loading multiple instances of UI loader containing
external SWFs on my stage. When user double clicks on the video
thumbnail, an instance of UIloader will be placed on the main
stage.The user can place as many UIloader instances on the main
stage. My aim is that if user puts any UIloader on top of already
existed UIloader, the existed loader will be replaced with the
placed loader. I am successful in implementing that by using
hitTestObject method for that. I am planning to provide enough
feedback to the user for this UIloader replacement process, so i
was thinking to change the border of the UIloader as soon as the
dragged UIloader hits the already existed UIloader.
Does anyone know how would I animate UIloader to give enough
feedback to the user that it is being replaced. Creating an
invisible movie and moving it wherever UIloader goes doesn't sound
much efficient.
Please help me out in figuring out this problem. Also
if anyone has better idea to give enough feedback to user, that
will also be welcome. Just to be little clear i have provided
little pseudo-code(below) of what i am doing here.
Any help will be highly appreciated.
Thanks

myUILoader.startDrag();
//Putting video on top of already existed videos
var trackChild:Number=container.getChildIndex(myUILoader);
var childContainer:DisplayObject=
container.getChildAt(trackChild);
for( var z:Number=0;z<=container.numChildren-1;z++)
var restChild:DisplayObject=container.getChildAt(z);
if(childContainer!=restChild)
if((childContainer.hitTestObject(restChild))==true)
//Show Animation during replacement
//how would i give feedback here
container.removeChild(restChild);

What is a Lopp Browser?
A typo I meant Loop Browser, sorry. On your iPad you can see the iTunes Library in the Loop Browser:
Open the Loop Browser
Tap the Loop Browser button in the control bar. The Loop Browser button is available only in Tracks view.The first time you open the Loop Browser, it shows the Instrument grid.
I was told by a sales person at the Apple Store at one of my One-on-One sessions, that Mac would not transpose nor change tempo because my "live music" was not a "midi" file.
GarageBand 10.0 will change the pitch and tempo of live recordings - midi as well as audio instruments, but not of audio files. But you need to enable the "Follow tempo and pitch" option in the track editor.
Then you can transpose the region using the "Transpose" slider.
And if you change the project tempo in the LED display after you enabled "Follow Tempo&Pitch" the recording will follow the new tempo.
You can test this with a new project created on your mac.
