[guan_zo]

I close the dialog  and then open，the dialog can not drag in ie8 when "modal: true",
$(function () {
        $("#div").dialog({
            width: 200,
            height: 200,
            modal: true,
            content: 'test',
            title: "title"
        });
        $("#btn").click(function () {
            $("#div").dialog("open")
        });
    });

Please try to override the $.fn.window.getMaskSize function.

Code:

<script>
$.fn.window.getMaskSize = function(target){
	var state = $(target).data('window');
	var inline = (state && state.options.inline);
	return {
		width: (inline ? '100%' : $(window).width()),
		height: (inline ? '100%' : $(window).height())
	};
};
</script>
