Sandbox button

I’m confused with option in sandbox settings ‘Automatically run unrecognized programs inside the Sandbox’

If I uncheck this option then I don’t see Sandbox button in alert window.
That is weird, I want to use Sandbox but at the same time I don’t want Comodo to auto-run some programs in sandbox. I thought that was the idea behind Sandbox button in alerts.
What I need to do in order to disable auto-run in sandbox and have Sandbox button in alerts ?
