IE Bug with widget-overlay at full screen designs

In IE 7, 8 is a small bug with full screen designs if you use css: body { height: 100%; width: 100%; }

Fixing this line in css

/* Overlays */

.ui-widget-overlay { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

with

/* Overlays */

.ui-widget-overlay { position: fixed; top: 0; left: 0; width: 100%; height: 100%; }

and now is running good in IE and as well in all other maior browsers
