plupload file browse dialog only open on firefox

I've just experienced an issue with plupload. Say that the file browse dialog open only on Firefox, other browsers doesn't work including IE 9, Chrome, Opera, I didn't test Safari though. Fortunately this thread told me where the issue comes from. You must put the browse_button inside the container:

        var uploader = new plupload.Uploader({
            runtimes : 'html5, flash, browserplus',
            browse_button : 'theUploadBtn', 
            container: 'divPlUploadContainer', // << 'theUploadBtn' must be inside this element!
            max_file_size : '2mb',
            url : 'file/upload/handler',
            multipart: true,
            flash_swf_url : '/lib/plupload/js/plupload.flash.swf',
            filters : [
                {title : "Image files", extensions : "jpg,gif,png"},
            ]
        });

However plupload still not work on Opera with this change
