Description
Consider the following test.

Initially we have root node with one level beneath. Node expansion adds another level with 2 nodes unless expanded node haв been expanded before (filled = true). But before expanding we destroy all subnodes (actually the test is a simplified version of building filesystem tree dynamically).
Now do the following: 1. Expand Folder1. 2. Drag Folder11 onto Folder12. Because expand() destroys all children including the one that has just been dragged, and then adds a sublevel we now have 2 subnodes Folder121 and Folder122. That is normal. 3. Now try drag ANY node. In IE 7.0 you will see the following message:
DEBUG: [Error: Unspecified error.] when calling onMouseMove$joinpoint$method on [object Object] with arguments [object Object] FATAL exception raised: Unspecified error.
In Firefox 2.0.0.11 no problems occur.
