In my online travels, I came across a "hack" that enables a link to close a window without that little warning that says, "The Web page you are viewing is trying to close the window.  Do you want to close this window?"  Here's an example of that with the warning:  close, done by using javascript:self.close().  Now here's a link to close the window without the warning: close, done by using javascript:this.focus(); self.opener = this; self.close();.  This code basically tells the window to say, "Hey, this window was opened by another window, which is actually this same window.  So I don't have to warn anybody about closing the window because somebody else opened it." #technology
