Working on an online registration site, and I need some javascript help. Basically, going back can break it at certain times, so we have decided to try and hide or disable the back button. I searched the 'net a bit and found many scripts for making chromeless popups, but I need something slightly different--I need something that will just take the chrome off once one goes to the site as it will be getting linked to from many places, some of which dont play well with js.

Any help will be greatly appreciated.
