Tipps und Änderungsvorschläge für meine Drag'n Drop - Klasse

[Gawin]

Ok, langsam wirds peinlich, hab den Fehler gefunden.
Aber irgent wie schaffen IE5.5-IE7 es nicht die DIV's mit "class='dragobj'" zu verschieben,
verschiebt aber die sachen mit "class='window'" wunderbar.
Der IE8 verweigert sogar glatt alles!!!
Aber ich weiss einfach nicht warum.

Hier die aktualisierte drag_n_drop.js:

                window.document.documentElement : window.document.body;  
    pos={X:null,Y:null};  
    if (typeof e.pageX == 'number'){  
        pos.Y = e.pageY;  
        pos.X = e.pageX;  
    }else{  
        pos.Y = e.clientY + body.scrollTop - body.clientTop;  
        pos.X = e.clientX + body.scrollLeft - body.clientLeft;

Die index.html is gleich geblieben ausser das "class='drag_obj'" zu "class='dragobj'" wurde. Demoseite findet Ihr wieder HIER.

Hoffe mir kann jemand helfen.
