Version: 0.70.90 (using 4.3.00 (KDE 4.3.0), MS Visual Studio 2008 SP1) Compiler: cl.exe OS: Microsoft Windows (unknown) release 6.1 In KDE 4.2.3, Kopete used to open a message window upon a single click over the contact. KDE 4.3.0/Windows Kopete requires a doubleclick. Please return (as an option) single click functionality to open a chat window.
Dear user, unfortunately Kopete is no longer maintained. Please migrate to another solution, e.g. for Jabber a possibility is Kaidan, for Matrix a candidate is NeoChat.
