Cancel and event queue interact badly on IE

[jdmarshall]

I have a sortable list with elements that get marked as unsortable until the changes have been saved on the server.

On IE, either because of differences in the event queue or just the slowness of refreshPositions, seems to queue up mouse drag events, so that a drag operation following another gets honored even though it gets ignored on other browsers.

What I suspect is happening is that on drag start, the positions get updated before the 'cancel' rule is applied. I think perhaps cancel should trump refreshPositions, no?

item.sortable( { cancel: '.inProgress', stop: function(event, ui) { saveChanges(); } });
