As I was developing an application with jQuery (latest version), my firefox browser decided to update itself to version 6. Right after that, I got the standard jquery ui "sortable" function not working properly. I tried on the jquery website and same thing. Tried with the demo files downloaded with the jquery ui bundle => same result. No hacks, no custo, just vanilla.

Here are the symptoms: starting the sorting (by clicking and dragging the mouse around), the sortable element sticks to the mouse pointer. Fine until there. But when releasing the left mouse button, the sortable element drops on its final position and suddenly, as I move the mouse elsewhere (no mouse buttons clicked) the last sorted element sticks back to the mouse and moves with the pointer.

Clicking somewhere on the page moves the sortable element back to the final dropped position but as soon as I move again the mouse, that element sticks again and does not drop.

Has anyone come over such a bug with firefox 6?

FYI, this sortable function was working like a charm on FF 5.0
