I'm trying to capture and handle the mouse dragging (mouse move with the left button pressed) activity on an IMG object. I wrote event to handlers for onmousedown, onmousemove and onmouseup. However, only onmousedown was called, the other two were always ingored. And when I drag the mouse, the mouse cursor changes to a "NO" cursor, as if it was trying to drag & drop the image to somewhere. How do I bypass or disable this default drag...
