I have a customer who is using GW Messenger 2.01 and it looks like when you close a chat windows and reopen it, you see only your replies and the other person's look like so:

11/02/2009 4:36:35 PM): 鄐<ㅦ慜獮੩屻潦瑮扴筬晜尰湦汩唠歮潮湷紻੽屻潣潬瑲汢㬠牜摥尰牧敥の扜畬づ紻尊捵就晣就て晜㉳‴楗桴䔠䝎 㽌灜牡紊਀}ļ嬈<付<렰<

Any idea of what maybe causing this.
