I'm using 2.0, I'm not in a huge hurry to upgrade right before I finish this
project :)
Thank you for offering help, I got it working by changing the TileList
attribute dragMoveEnabled="true" (I didn't realize this could be turned on
when using custom drag and drop handling).

are you using flex 2.0 or 2.0.1?
I have an application using drag and drop and need to move the items
within the TileList, it was working just fine in version 2.0, now since I
updated to 2.0.1 it doesn't move the items anymore but instead makes a
copy.
Basically I want to order the Items of the TileList by dragging them, but
I also want to drag items from a different component. As I said it worked
with flex 2.0.
Here is the code:
<?xml version="1.0" encoding="utf-8"?>
<mx:TileList
xmlns:mx="http://www.adobe.com/2006/mxml";
backgroundAlpha=" 0" backgroundColor="#FFFFFF"
itemRenderer=" renderer.ProjectThumbnail"
dragEnabled="true"
dragEnter="doDragEnter(event)"
dragExit="doDragExit(event)"
dragDrop="doDragDrop(event)"
dragOver="doDragOver(event)"
mouseDown="dropInitiator = DragManager.MOVE;"
dragMoveEnabled="true ">
<mx:Script>
