Click the Apply button to save the current entry to the temporary file. After the entry is saved, the session log will be displayed, and the window will be prepared to allow you to create a new entry.
A Warning dialog will display if the current entry is unbalanced, or if the current entry has no detail. In either case, the save will not be performed.
When the session log is displayed, there is no current entry, since the log is only displayed after the current entry has been saved or voided.
