jqDnR dragging problem with Jquery 1.4

jqDnR dragging problem with Jquery 1.4

 With jquery 1.4, I am experiencing a problem with the jqDnR plugin.

I am using this plugin to make an element draggable. One of the problem is that the dragging function do not work with jquery 1.4 (but worked well with the previous version of jquery). 

It seems that in the plugin, there is somewhere: "$().mousemove($.jqDnR.drag).mouseup($.jqDnR.stop);E.css({opacity:0.8});" and $() is no longer valid.

So I put $(this) instead (or $("#rubrique"), which is the id of my element) and it works a little bit, but still not as before, because now, when I drag the element, the mouse is too fast and the element cannot follow the mouse, and as soon as the mouse is not onto the element, it is not dragged anymore. I have to get my mouse back onto the element and move it slowly to drag it again. And worse, if I release the click outside the element, the element is never released from the dragging.


I don't know if I'm explaining it well enough, but if you have any solution, let me know, and thank you a lot!
