Description Jeff Kobal CLA 2002-08-08 12:30:48 EDT 
Scenario: Select a file in the Navigator then File->Rename.  While the 
name-editor window is in focus, select File->Rename again.  The name-editor 
window won't close, and the Navigator will become completely unresponsive.
Comment 1 Jeff Kobal CLA 2002-09-10 10:19:55 EDT 
Is there any progress on this problem yet?
Comment 2 Lynne Kues CLA 2002-09-10 18:09:04 EDT 
I don't see the "completely unresponsive" behavior, but the given scenario can 
lead to an NPE in build 20020827.  Do these steps:

1. Select item.  File==>Rename.
2. File==>Rename again while edit widget still has focus.
3. Select another view so that focus leaves Navigator view.
4. Select an item in the Navigator view.  Get NPE.  Stack as follows:

Yes, I'd noticed the abend after getting into the hung state, and figured it was 
a side-effect of the hung Navigator.
