Well,... If you are using IE anyway, there is a way. I'm not sure I even want to post it here because it is so obnoxious I would consider it a bug, in a sense. It shouldn't be allowed. function dosomethingincrediblyobnoxious() { window.open("thispage.aspx") window.open("thispage.aspx") window.open("thispage.aspx") window.open("thispage.aspx") } If you do this, you can't alt/F4 fast enough to close all the windows, it is really obnoxious. This would be a great way of keeping people from ever coming back to your site.
