What is the name of the Skype-style jabber client that does not use separate chat windows?

Question

Messengers

You need a jabber client for Windows, preferably for Linux too.
All jabber clients I've seen use a separate window for chat, like icq.
Tell me, which client uses the Skype style when the chat is conducted in the same window as the contact feed (roster), and not in tabs?
