>> The problem is with the DropTarget Enter/Exit events. For real heavyweights they are generated by native code. For lightweights - in shared code. But for AWT components they should be generated in CDropTargetContextPeer.
>> Before the fix these events could be generated incorrectly: sometimes duplicated events were sent (this broke autoscrolling) and sometimes events were not sent at all - this caused NPEs in the shared code.
>> The insideTarget boolean was replaced by a reference to DropTarget to handle nested components correctly.
