Hi

 

Because for Flash/Silverlight component, they do not allow api call to open the dialog.

 

So when you use button.click() function , it will be block and show warning to let user click the Flash/Silverlight  again.

 

If you just want to hide the queue table, you can declare this function:

 

<script>

function CuteWebUI_AjaxUploader_OnQueueUI(list)
{

    return false;
}

</script>
