Autocomplete suggest size is larger in IE8 than in Firefox

Autocomplete suggest size is larger in IE8 than in Firefox

Hello,

I use jquery ui 1.8.2 for make an autocomplete in a modal dialog. In IE8 the width of the suggest window is 1380px and in Firefox it's 188px. I've made tests with safari, chrome and opera. Only in IE width is so large. How can I set the size of autocomplete suggest window ?

this my code :

$("#ville").autocomplete({
                    source: "http://myhost/magento/js/jquery/ui/php/ville.php",
                    minLength: 1,
                   
                });

Thanks a lot,

James
