If I were to hazard a guess I would think that this approach would not work as it could be a security hole. As long as you can determine the method used to close the window you can manipulate the DOM to prevent it. I.e., at some point a script is deriving the window object. Figure out how and you can prevent it. But also keep in mind my previous caveat--doing so could cause the site to not function properly. > Thanks.
