Jquery AutoComplete - Exact browser version it works ?

Jquery AutoComplete - Exact browser version it works ?

I have started working with jquery for one of the project. For the autocomplete plug in, it works perfectly with Firefox 3.0.10 but it does not work with IE 6.0.

I was under impression that it works IE 6 and above version.

Please let me know what are the IE version works perfectly with autocomplete ?

Thanks
