I really do not like the Windows Live Messenger interface, and every time they revise it, it gets even worse. I want to use a replacement, ...
but I don't want to lose the message history.
My company uses Messenger for discussion of technical problems, and I often need to visit the history to find a previous discussion.
Is there any substitute client that will use/continue the message history? It must also support file transfer.
I'm running Windows XP/Pro, as required by my company.
