trying to click inside the JUnit view.
I lost the toolbar and the view caused another exception on close.
I don't have real steps to reproduce as it happens when I was not expecting to do a D&D operation.

For M3 I'm going to comment out the TB Drag/Drop agents. This functionality isn't finished and relies on the model *not* being torn apart and re-created on startup (at the moment any changes will be lost on a restart).

Committed in >20101028. Commented out the TB DnD agents.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

This is a mass change to close all e4 bugs marked with "stalebug" whiteboard.

If this bug is still valid, please reopen and remove the "stalebug" keyword.
