Draggable unable to be dragged outside window in IE7

Draggable unable to be dragged outside window in IE7


Using jQuery UI 1.7.1 (on WinXp with IE7)
I've been trying to get a Draggable div to be dragged outside the
window viewport in IE7,
as it can be in the following browsers:
Chrome 1.0.154.48, Opera 9.63, Firefox 3.0.8, Safari 4beta.
In IE7 the drag gets stopped prior to the div leaving the viewport.
Try in
jquery-ui-1.7.1/demos/draggable/default.html
dragging the Draggable left, out of the window in IE7 and then in
one of the other browsers listed above.
Can this be fixed?
