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>
