#1: DZ a file or named buffer against an "Untitled<n>" buffer.
Close DZ.
Open DZ Again: That diff doesn't appear in diff history.
Note: You can click "Save..." to save the session, and that works - with the untitled path being saved as blank - seems appropriate.
#2: DZ a file or named buffer against an "Untitled<n>" buffer.
Make a change to the Untitled<> buffer in DZ.
Close Diff
DZ Prompts with:
---------------------------
SlickEdit Pro
---------------------------
Do you wish to save changes to ''
---------------------------
Cancel &Yes &No
---------------------------
Click "NO" and things work as expected.
Click "YES" and you are prompted for a filename to save to.
That file is created, but not associated with the Untitled buffer.
The Untitled buffer stays loaded and the newly created file is not opened.
