The Snapshot Comparison dialog allows you to specify a name for a newly created snapshot.
The dialog is initially displayed with a suggested default name for the snapshot comparison (as shown above).
If you would prefer a more informative name, type your own snapshot name.
•Automatically compare most recent... 
All future snapshots will be named automatically and compared automatically.
The comparison will be between the penultimate snapshot and the most recent snapshot. You won't see this dialog again.
If you change your mind and wish to start naming your snapshot comparisons again, go to the Snapshots Display Settings dialog to change the setting.
The first and second snapshots default to the penultimate snapshot and the most recent snapshot.
•First snapshot The snapshot to be compared against.
•Second snapshot The snapshot that you think may contain leaked objects.
