This issue would mostly occur when you will be having a conversation with someone, close the window and that person later on decides to reply to you in the same window.
Cause: Unknown, even though it looked like the serialization issue that was fixed by MS long back.
Solution: Earlier I tried Security Update for Microsoft Communicator 2007 R2 (KB2827753), I didn't notice this issue but it started to occur again.
Later on it got really worse and workaround was to leave all IM windows open.
Final fix so far is to :
Remove MS Communicator, install it back again and patch it with following:
NOTE: Not being on latest security patch opens up security hole. You want to make sure you work with Microsoft on this issue if you continue to face this issue.
