disismi on "Setup scripts not protected"

Hi

I have this warning in my dashboard:

Your Setup scripts are not protected.

The Setup environment is not totally secure, you should protect the scripts to thwart hackers. Use the Setup » protect scripts button in the Admin section of the Utility functions.

When I press the button 'setup>>protect scripts', I see this: Setup files protected.

But the first message (Your Setup scripts are not protected) never goes away.

So, are my files protected or is there a way I can do this manualy?

tnx
