Using jQuery, when you set a blur event on a text box and set another element as draggable, when you click the draggable element, the blur event does not fire in FireFox. IE is a little better, you get the blur event but you don't get the click event on the draggable element.
If you don't specify the cancel: "" in the draggable constructor, you will get the blur event to fire, but then the element you want to drag is not draggable.

The console.log lines are for FireFox's FireBug plugin.
