Version: (using KDE 4.3.3) Installed from: Ubuntu Packages If I receive a call which I do not take, the window remains. This ok, as long as the same person does not trie it more often. Then for every call there is one of this call window. This behaviour should be changed. Either just by replacing it or may be better replacing it by a notification with a list of "missed calls".
Dear user, unfortunately Kopete is no longer maintained.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.
