Large corporations have strict software standards, and v4.73 is the current standard. When right clicking the shortcut, there is not an option to open in a new window. We've been using a workaround by launching a new session of Netscape, and then click the shortcut so that it uses that new window instead of the one I want to continue using. We would prefer to launch the shortcut and have it open a new session in a new window by default.
