   Arguments:
    pageToLoad - The URL of a page to load in the browser window.
                 This can be a relative URL or fully qualified.
    winName - 	 Name of the new window.

    height - 	 The vertical size of the new window.
    center -     toggle centering on 4.0 browsers.
                  1=centered window 0=no centering

    Values in the "args" section below can all be toggled in the
    same fashion as the center toggle.  Just modify the appropriate
    value in the args section to be either 0 or 1.

    A call to this function might look like this:
    <a href="javascript:openAWindow('ice.html','ice',375,250,1)">Ice</a>
