lockdown to browser window only

We have read the manual up and down and played now with the setup for a week but can't figure out to set it up.
All we need is to lockdown the computer while it should run/start only the browser window IE with a specific site. We do not want a circle dock or start menu, just the browser window in fullscreen mode.

Any help would be appreciated.

Kind Regards

You need Secure Lockdown - IE Edition. You're using Secure Lockdown - Multi App Edition. Note that white listing using IE only works on Windows 7. The white listing feature (Allowed Sites) does not work under Windows 10.
