I implemented the jquery sortable plugin to be able drag and drop list-items between two lists. I apply some styles to my list items like putting different background for each list. the issue is when I drag one item from list A to list B most of the time I see the dragged elements but every now and then when i start dragging the element disappear from the screen I can still drag it but I cannot see it and suddenly appears again when I drop it. The only i am able to see in those cases is the mouse pointer.
here is my code:
Note: the switched var tells me if the item changed from list A to B or vice versa!
Note2: in the same page I load EXTJS and jQuery but I am not triggering EXTJS events when dragging and the list items are plain
var switched, senderID;
