Amazing Frameless Popup Window with No Titlebar
Say goodbye to ugly Windows popups! In IE4 and later, this cut-and-paste script launches a popup window without the Windows frame or titlebar (that is, a "containerless" window). In other browsers, it launches a standard popup window. Position, width, and height are settable. Automatic closing of the window on leaving the page may also be optionally set. <b>Update:</b> Added an addendum showing how to simply auto-center the window on the screen.
