Adding to safe sites or programs doesn't prevent a security prompt from occurring. Is there a way to resolve this?
To stop the IE ESC messages from being displayed.
1. Start Internet Explorer on the machine experiencing the problem (where the Spotlight client is installed).
2. Go to the Tools | Internet Options menu and open the Security tab. Select the Trusted sites item and press the Sites button and add the about:security_Spotlight.exe to the list of trusted sites. When completed, press the close button.
3. Restart the Spotlight client.
