Enabling or Disabling Confirmation before
Discarding Unnamed Trace
By default, each time you press the Start button when a trace has not been
saved, the application prompts you to confirm if you want to save the trace
or not.
If you disable the confirmation, the application will discard the unnamed
trace directly.
To enable or disable confirmation:
1. From the main window, press Setup, then select the General tab.
2. If you want to confirm the deletion each time you press Save, select
the Prompt before discarding unnamed trace box.
OR
If you never want the application to discard the unnamed trace
automatically, clear the box.
3. Press Apply to confirm the changes, then OK to return to the main
window.
