They are tricking you into believing there is no source code byleaving enough lines black at the top you dont realize you need to scroll down, you only see a blank page. As for the menu being removed, it is accomplished by Jacascript tags. You can get these free at many javascript sites. I have tried a completely fullscreen viewing with a "exit" button added for the viewer to close out the screen. This works good, but nosey people like me get intrigued as to the "how" part and you could attract more attention than before. Unless you are using state of the art tags, or keep something very important in your source, you might want to rethink putting so much time into your source hiding capabilities. http://javascript.internet.com/ has a large supply of tags for every conceivable use, I suggest browsing them for some ideas on how far you want to go.
