Possible Bug with Grid Server Templates and drag and drop?

[Peter Felice]

Hi, Not sure if this is reported or not, but i couldn't find any reference.

Whenever you try to drag a gird column (either with Groupable or Reordable) that has a server template set on it, a javascript exception will be thrown "Object has no method 'prepend'". It seems to originate in the telerik.draganddrop.js file here:

$t.dragCue = function (html) {
    return $('<div class="t-header t-drag-clue" />')
        .html(html)
        .prepend('<span class="t-icon t-drag-status t-denied" />')
        .appendTo(document.body);
}

Since the method is called for every movement of the mouse while dragging, it can be thrown 100's of times in a single movement. Is this a known bug or do i have something set up wrong on my side? I am using version 2010.3.1110

Thanks,
