This provides a way to allow or deny user access to window resizing facilities.
This switches the resize feature on and off, which is something you can control in new windows you create with the open() method when you specify the resizable feature.
Your script needs UniversalBrowserWrite privileges to use this method.
Some platforms will not support this facility due to the way their window manager operates. This is likely to be supported on desktop systems and less likely to work on workstations that use X-Windows.
