wichtige ergaenzung

.. und uebrigens muss in der funktion "mediapopup(...)"
   zur methode "open(..)" auch einentsprechendes objekt stehen

also nicht:

function mediapopup(file,width,height,type) {
        newwidth = width + 36;
        if (type == "qt") { newheight = height + 48; mediaheight = height + 16; }
        else { newheight = height + 36; }
        var MediaWin = open

-------------------------^^^^

("/assets/media.html","MediaViewer","width=" + newwidth + ",height=" + newheight + ",screenX=100,screenY=100,resizable=yes,scrollbars=yes,menubar=no,status=yes");
...
}

sondern:

var MediaWin = null;

function mediapopup(file,width,height,type) {
        newwidth = width + 36;
        if (type == "qt") { newheight = height + 48; mediaheight = height + 16; }
        else { newheight = height + 36; }
        MediaWin = window.open("/assets/media.html","MediaViewer","width=" + newwidth + ",height=" + newheight + ",screenX=100,screenY=100,resizable=yes,scrollbars=yes,menubar=no,status=yes");
...
}
