This is a very popular script that frame designers "accidentaly" make. You can malnipulate what happens to the person's screen.
Here is something interesting with the Opening. You Have three options you can malnipulate.
("URL","Window_Name","Window_Attributes")

There are a few Window Attributes you can use. They are
toolbar - Controls the display of the button bar
location - Controls the display of the current location field
status - Controls the display of the status bar
menubar - Controls the display of the menu bar
scrollbars - Controls the display of the scroll bars
resizable - Controls whether the user can change the window's size
width - Specifies window width (in pixels)
height - Specifies window height (in pixels)
