Hi,

I am trying to implement some custom drag and drop using javascript.  
However, in Firefox, the drag and drop extension seems to interfere with  
my custom handling of onMouseDown, onMouseMove and onMouseUp.

Once I start to drag the mouse (left-mouse-down + move a few pixels)  
firefox shows a drag-forbidden symbol (circle with a diagonal bar  
inside).  
Does anybody know how to disable this firefox extensions as it makes no  
sense in my case.

Best Regards  
Peter
