How to disable dropping text from word

Now I can grab the drag events and I can disable It.

Here is my solution (put this code to the config.js):

CKEDITOR.on('instanceReady', function(ev)
    {
        var editor = ev.editor;

        var disableEvent = function( evt ) {
            evt.cancelBubble = true; 
            evt.returnValue = false; 
            evt.preventDefault(); 
            evt.stopPropagation();

            return false;
        };


        if (editor.document.$.addEventListener) {
            editor.document.$.addEventListener( 'dragover', disableEvent, true ) ; 
            editor.document.$.addEventListener( 'drop', disableEvent, true ) ; 
        } else if (editor.document.$.attachEvent) {
            editor.document.$.attachEvent( 'ondragover', disableEvent, true ) ; 
            editor.document.$.attachEvent( 'ondrop', disableEvent, true ) ; 
        }
    });

This is tested and working on Windows 7 Firefox 3.6/Internet Explorer 8/Google Chrome 8

But with this solution I cant drag images to the good position
