Unable to drag a field out of a metabox to disassociate it from a content type

[GoogleCodeExporter]

What steps will reproduce the problem? (Be specific enough so that someone
else can make the plugin fail for themselves. Remember: the issue can't
be fixed if it can't be reproduced!)
1.  Define post type
2. Define custom fields, add them to the post type
3. Manage the post-type's custom fields.  
4. Try dragging a field out of the main (default) metabox and into the "unused" 
box at left.  

What is the expected output? What do you see instead?

The "Inactive" box does not work as a target for the drag-and-drop operation.  
It needs to stick and when the page is saved, that custom field should be 
disassociated from that post-type.

Can't reproduce this.  I'm able to drag fields in and out of all metaboxes -- 
once I click save @ bottom, the changes stick.
