Netscape will allow you to open a Frame in an New Browser Window.
This is particularly important if the Frame is "crowded" with information!
From the Netscape Frames Example: http://home.netscape.com/comprod/upgrades/index.html
(or Frame Page of your choice)
"Click-inside" the Frame...,
you would like to open in a New Browser
Window...
A "black border" around the Frame (Pane)
will appear.
From the Netscape Browser Toolbar..., Choose File, then "click-on" New Web Browser.
When you are finished with the Frame in the New Browser Window..., "Click-on" the Close Window Icon..., the "X" in the (upper right hand) Corner of the Netscape Browser Window.
