I have a page with some droppable <td> elements and a dialog over the page with some draggable elements. When I drag an element over the dialog that is over a droppable <td>, then elements drops inside it even if it is still being dragged over the dialog. Is there any way to prevent drop while the draggable is still over the dialog? For an example, see here: http://www.albanx.com/drop.jpg
