Messager progress not showing up

[Wojak]

Hi,
When there is a window open, the messager won't show up, as if it was behind that window or it wasn't showing at all.

Please look at this example. It works fine.

Code:

<div class="easyui-window" style="width: 400px;height:200px;padding:20px">
	<button class="easyui-linkbutton" onclick="showprogress()">Show Progress</button>
</div>
<script>
	function showprogress(){
		var win = $.messager.progress({
			title:'Please waiting',
			msg:'Loading data...'
		});
		setTimeout(function(){
			$.messager.progress('close');
		},5000)
	}
</script>

Ok, but after some investigation I found that after declaring this messager I use

Code:

$.ajaxSetup({ async: false });

and some computers with the same browser show this progress and some don't
