When calling .buttonset() on a formatting div which containins the items I wish to buttonize, if using a class for the individual buttons that I have called .buttonset() on, a subsequent selection of it's class to set it's disabled attribute has no effect!
There seems to be a bug with either my code or that of the draggable UI element. When I drag a draggable UI element onto a droppable element, the draggable item does not "stay in place", it "moves" across the screen and sometimes off the screen if, when I am placing it, I drag it further to the right.
