tiny modify to animate the progressbar


~ line 120 in ui.progressbar.js
replace
this.bar.width(this.pixelState);
with
var ScriptEngineMinorVersion = ScriptEngineMinorVersion || function()
{return 9};
var lowerThanIE8 = (ScriptEngineMinorVersion() < 8);
if ( lowerThanIE8 ) {
    this.bar.width(this.pixelState);
} else {
    this.bar.stop().animate({width:this.pixelState},300);
}
Since I use 6 progressbar same time, it deny animation in IE6/7 for
performance issue.
If you want to have animation, you could modify it like code above. or
only
this.bar.stop().animate({width:this.pixelState},300);
300=duration in ms.
