// captureClick :: calls newWindow, and returns false so that the href in the link doesn't activate.

//                 When this is used with a certain anchor format we can have nice sized javascript windows,

//                 or normal new windows if Javascript is turned off



function captureClick(url) {

    newWindow(url);

    return false;

}





// newWindow :: creates a new window pointing to a given URL.  The window has the features we want.



function newWindow(url) {

    var nw=window.open(url, "emslWindow", "scrollbars,toolbar,menubar,location,status,resizable,width=550,height=450");



    if(parseInt(navigator.appVersion) >= 4) {

        var nwLeft = (screen.availWidth - 550) / 2;

}





//  moveWindow :: given a window object, moves the window to the given coordinates

//                This generates errors in IE4 and Netscape 4; they don't like the exception handling.

//                But it's necessary to support newer browsers, so we leave it in.
