designMode with absolute position

Hi all,

I am working on site builder application which provides user to easily
drag and drop elements which are absolute positioned DIVs & images,
the IE version is ready. Now I am working on firefox version and I
need the same behavior as IE have. Unfortunately firefox didn't treat
the absolute elements when in designMode as IE did,

1) Events aren't registered.
2) The handler is really ugly which appears on top. I am trying to
make the designMode on and off dynamically
    and firefox showing the handler, either designMode is on or off.
3) Sometimes the handler disappears while borders remain there. So you
can't drag objects.
4) If you select an element, handler will not leave it until you
select any other element.


Thanks in advance,
