Problem selecting adreses

Hi,

I have a very curious problem with 6.5.4 client. When I make a new mail and i want to search for a specific adres i push the button adres, then the “Selecting Adreses” pop up its open, if a fill the field “Find names starting with” with the letter “CI” i CANT go to “ci***” adreses but if I just pick with the mouse on the list of adres and write “CI” then show me automaticlly the “CI*” adreses.

This problem only is showing in all 6.5.4 clients, not in 6.5.3

Can anyone explain me why this problem appear and how to fix it pls.

Thx in advance.

PD: Sorry for my bad English, I hope u can understand my problem.
