Drag and Drop of Mobile Phones etc.

One of the problems with mobile phones with capacitative screens is that the drag and drop doesn't work because the phone thinks you're trying to move the image around rather than the item. 'Holding' the item by maintaining the pressure is also risky as that brings up a context-sensitive dialog box for many browsers. One possible way would be to make use of the 'Double-Click' option in JavaScript to select the item. This might also work in the standard ones too, although 'holding' IS much more intuitive. There is a javascript ondblclick() function that could, presumably, be used for this.
