I was attempting to move the Properties view over the Hierarchy view and only 
the top part of a vertically orientated Hierarchy view was highlighted and the 
D&D icon was the folders (and not the arrow).
Comment 2 Stefan Xenos CLA 2004-05-08 06:07:55 EDT 
The original bug is a duplicate of bug 58042 (fixed)

However, the NPE from comment 1 seems to be something different. Keeping this
open until the NPE can be investigated.
Comment 3 Stefan Xenos CLA 2004-05-08 06:17:41 EDT 
The stack trace in comment 1 is a dupe of bug 56816
